Evaluating the Effect of Sewage Sludge on Bioactive Components of Momordicacharantia

Momordicacharantia L. belongs to the family Cucurbitaceae. This plant has widely been reported for use in traditional medical systems for the treatment of diabetes, rheumatism, intestinal gas and malaria. The ethnicity of M. charantiais Asia, Africa and some parts of Europe where it is considered edible. Sewage sludge, a by-product of waste water treatment plant, contains several nutrients. These nutrients are known as beneficial for the better growth and good yield of the plants. The objective of this study is to optimize soil with different ratios of sewage sludge for increased growth of more

Ultrasonic Powered Hydrothermal Modification of Coal Fly Ash to Cost-Effective Zeolites

Coal fly ash (CFA) waste is one of the anthropogenic materials having detrimental impact as particulate and leachate contaminant. Dumping of such solid waste into landfills and other improper waste management conduct can be lethal for environment. In this work CFA waste was attempted to modify into zeolites using ultrasonic assisted hydrothermal and conventional heating approaches. The conventional and ultrasonic assisted synthesized zeolites showed entirely different cation exchange capacity (CEC) and morphology. However, FTIR and XRD patterns of zeolites synthesized by both of techniques more

Lithium Recovery from Water Resources by Ion Exchange and Sorption Method

Demand to lithium rising swiftly as increasing due to its rapidly increasing dosages diverse applications such as rechargeable batteries, light aircraft alloys, and nuclear fusion. Lithium demand is expected to triple by 2025 driven by battery applications, specifically electric vehicles. To ensure the growing consumption of lithium, it is necessary to increase the production of lithium from different resources. Natural lithium resources mainly associate within granite pegmatite type deposit (spodumene and petalite ores), salt lake brines, seawater, and geothermal water. Among them, the more

Utility of Spectroscopic Studies for Quantification of Cefditoren Pivoxil in Commercial Samples

The current study is devoted to suggest new simple spectrophotometric probes for the estimation and quantification of cefditoren pivoxil (CFP) either in authentic or in commercial samples. Three simple kinetic and derivatize sensitive spectrophotometric methods were established. Two kinetic techniques (method A) and (method B) were based on the estimation of CFP using the oxidation properties of alkaline potassium permanganate at ambient temperature and the relation between the reduction in the absorbance of KMnO4 and the added CFP were also investigated. The intensity of absorbance (A) of more

Theoretical Study of the Complexation of Lidocaine by α- and β-Cyclodextrins

Structure and stability of an eventual inclusion complex formed by Lidocaine and two cyclodextrins (α- and β-CD) were investigated using molecular mechanics and quantum-chemical methods in the gas phase and in water. The molecular docking and quantum chemical calculations results show that no inclusion complex is formed between α-CD and Lidocaine molecule, while the conformational research allowed observing two minimum-energy structures between this molecule and β-CD. From a potential energy scan, a partial inclusion of the two ends of Lidocaine by the secondary face of the cavity of β-CD is more

Selective Removal of Hg2+ Ions from Water Using New Functionalized Silica Resin: Equilibrium, Thermodynamics and Kinetic Modeling Studies

In current study, the diphenylaminomethylcalix[4]arene (3) was synthesized and immobilized onto silica surface to prepare a selective, regenerable and stable resin-4. The synthesized resin-4 has been characterized by FT-IR spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX) and Brunauer-Emmett-Teller (BET) techniques. To check the adsorption capacity of resin-4, the batch and column adsorption methodology were applied and it has observed that the resin-4 was selectively removed Hg2+ ions under the optimized parameters. The maximum adsorption capacity was more

High Sensitivity Sulphite Membrane Selective Electrode and its Application

In this study, the new sulphite sensitive ion-selective electrode (ISE) was prepared. The ISE was prepared from a combination of 5% perfluorooctanesulfonic acid (PFOS), 40% PVC and 55% dibutylphthalate (DBF).The sensitivity of the ISE to 1.0x10- 7-1.0x10-1 M sulphite concentration was 58 ± 4 mV. Electrode sensitivity was characterized. The response time of this electrode is short and 30 s. The lifetime of ISE was approximately 210 days when used five times a day. It was determined that it can work at any pH value. It is not sensitive to anions and cations that may be present in the more

A Novel Magnetic Nanocatalyst Fe3O4@TiO2-H5IO6 for the Green Synthesis of 4-Substituted-1,5-benzodiazepine Derivatives

In this study, periodic acid-functionalized magnetic support (Fe3O4@TiO2-H5IO6) as a new, benign and recyclable nanocatalyst was prepared by anchoring / periodic acid onto TiO2-coated nano-Fe3O4. This catalyst was applied to achieve a high-efficiency, low-cost and eco-friendly approach for synthesizing 4-substituted-1,5-benzodiazepines with the multicomponent reactions of aromatic aldehydes, o-phenylenediamine, and dimedone. The / periodic acid group on Fe3O4@TiO2 possesses both Lewis and Brønsted acidity, which is responsible for the high catalyst activity. The obtained results show that the more

Synthesis, Crystal Structure and Anticancer Activity of Substituted Quinazoline Derivatives

News series of substituted quinazoline derivatives has been synthesized from 3,4-dihydro-7-methoxy-4-oxoquinazoline-6-yl acetate (1) by five-step procedures including chlorination, amination, hydrolysis and etherification. The structures of target compounds were confirmed by IR, 1H-NMR, element analysis and single-crystal X-ray diffraction. The results showed that the compound 8c exhibited remarkable inhibitory activity against MCF-7 cell lines with inhibition rate value of 38.45 %, which was comparable to that of the positive control Gefitinib (inhibition rate = 13.25 % for MCF-7). The more
