Adsorption of Fluoride from Aqueous Solution by Zirconium-Modified Artificial Zeolites: Kinetics, Thermodynamics and Mechanism

Artificial zeolites (AZ) and AZ modified with zirconium cation (AZZ) were fabricated in this work. AZ and AZZ, which were characterized by SEM and XRD, showed that AZZ was the composite of AZ and ZrO2. The adsorption kinetics and isotherms of AZ and AZZ towards fluoride removal in water were consistent with the Langmuir and pseudo-second-order models, respectively. AZZ had better fluoride adsorption capacity than AZ. The maximal adsorption capacity of fluoride onto AZZ reached up to 128.2 mg/g. Moreover, the thermodynamic studies illustrated that the adsorption procedure was spontaneous and more

Carbon Paste Electrode Modified with PMBP: A Sensitive Sensor for Electrochemical Detection of Acetaminophen

In this present work, a sensitive electrocatalytic modified electrode based on 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP)/multiwalled carbon nanotubes (MWCNT) modified carbon paste electrode (CPE) was successfully developed. Electrochemical impedance spectroscopy, square wave voltammetry, chronocoulometry and cyclic voltammetry were used in prompt to evaluate the PMBP/MWCNT/CPE electrochemical capacity in detecting acetaminophen (APAP) in 0.1 M PBS pH 6.4. Under optimized conditions, PMBP/MWCNT/CPE displayed a well-defined electrocatalytic activity towards APAP oxidation in the linear more

Poly (ether sulfone) (PES)/polystyrene (PS) Thermoplastic Polymer Blend: Molecular Dynamics (MD) Simulation Methods and Experimental to Miscibility Evaluation

In this study, poly (ether sulfone) (PES)/polystyrene (PS) thermoplastic polymer blend miscibility was looked at using both molecular dynamics (MD) simulations and experiments. In particular, the parameters of the Flory-Huggins interaction and the heat of mixing of poly (ether sulfone) (PES)/polystyrene (PS) blends at different compositions were calculated from MD simulation. For the PES/PS blend, both differential scanning calorimetry (DSC) and MD simulation showed that they are immiscible at PES/PS: 80/20,60/40 ratios. The degree of compatibility of the 20/80 and 40/60 PES/PS blends is more

Development Metronidazole Nanocomposite as Anti-inflammatory Agent for Athletes using Full Factorial Design

This work considers the optimization and characterization of metronidazole-calcium alginate nanoparticles (MET-AlgNPs) by an ionotropic gelation technique. The effect of the amount of sodium alginate (Alg), metronidazole, and calcium chloride (CaCl2) as the factors affecting drug loading efficiency (LE), particle size and potential of formulations were optimized and analyzed by using multiple regressions. These formulations were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), zeta size and potential, scanning electron more

Documentation of Ethnomedicinal Uses of Wild Plants Growing in Kodo Mountain by Kurdish Tribe of Iraq

Medicinal plants have a long history of different uses and are still of great importance in the daily life of the Kurds living in the Kurdistan province of Iraq. The present review provides comprehensive phytochemical and pharmacological information about medicinal plants growing in the Kodo Mountain area. In fact, no systematic study of the bioresources from this unique region has yet been reported in the scientific literature, even if local villagers have been consuming several plants as nutrition and ethnomedical food for centuries, until today. The data reported in this paper were more

Chromatography Free Synthesis of Reversed N-Triazole Nucleosides Starting from D-Galactopyranose using 1,3-Dipolar Cycloaddition Reactions

A chromatography free, four-step strategy has been developed to synthesize reversed N- nucleosides (4A-D) starting from -D-galactopyranose. The triaozle moiety served as heterocyclic part of nucleoside was created via 1,3 dipolar cycloaddition reaction between sugar azide (1,2:3,4-di-O-isopropylidene-6-deoxy-6-azido- -Dgalactopyranoside, 3) and terminal alkyne. Sugar azide 3 was obtained from 1,2:3,4-di-O-isopropylidene-6-tosyl- -Dgalactopyranoside (2). Purification of products was carried out through solvent-solvent extraction and/or crystallization techniques. This is an example of click more

Ozone Assisted Photocatalytic Degradation of Textile Wastewater

In present research, photocatalytic degradation of textile wastewater was investigated through the combined effect of ozonation and photocatalysis processes. Catalytic acids in the nano-particle form under moderate reaction conditions were used for the successful disintegration of contaminants in textile wastewater which in turn increases the process efficiency. Moreover, the combined effect of the photocatalytic-ozonation process after secondary treatment of textile wastewater on discharge requirements of zero discharge hazardous chemicals (ZDHC) by Road to Zero was also studied. Different more

Metal Binding Studies of Soil Extracted Humic Acid with K (I), Zn (II) and Fe (III) ions

: Physico chemical parameters of soil samples collected from agriculture lands of Taluka Sobhodaro District Khairpur, Sindh, Pakistan were examined to check the quality of soil. Moisture contents percentage, pH and EC values indicated that texture of soils is mostly silt- loam type having water holding ability hence can be considered as good fertile land, beneficial for crops. Humic acids (HAs) were extracted from soil samples by International Humic Substance Society(IHSS) method. HAs form biogeochemical cycle due to presence of electron clouds resultant macro and micro nutrients, transferred more

Physicochemical Characteristics and Dyeing Properties of Novel Cellulosic Fibers Derived from Sustainable Agricultural Waste

Development of new innovative sustainable fibres from agricultural waste are in great demand these days. For the expansion of these fibres at commercial level, understanding about physicochemical properties of these fibres and specifically their dyeing behavior is essential. In this consequence, in the present study, a natural lignin-cellulosic fibers were extracted by a simplistic route, from lotus silk. The fibers were turn in to yarn by hand twisting and then natural as well as chemical dyeing was performed by the standard dyeing method established for cotton dyeing. Natural henna dye, C.I more

Arduino Controlled Catalytic Pyrolysis of Plastic/Municipal Waste to Higher Hydrocarbons

Worldwide, the broad usage of plastic has resulted in the massive production of plastic pollution. In this work, it was demonstrated that municipal plastic waste could be converted into valuable liquid products. This study shows the catalytic and non-catalytic pyrolysis of low-density polyethylene (LDPE), polypropylene (PP), and high-density polyethylene (HDPE). Pyrolysis was carried out in the absence of Oxygen, and three types of fractions: gas, liquid, and solid residues were obtained. The proportions of liquid or gas residue depend on the operating conditions such as temperature and the more
