Prediction of Succinic Acid Extraction Efficiency in the Emulsion Liquid Membrane by using Machine Learning Techniques

This research aims to predict succinic acid concentration in the external phase during the emulsion liquid membrane process by using artificial neural networks along with a popular alternative method: k-nearest neighbor technique. The solute concentration values can be predicted by the proposed method without performing a great number of emulsion liquid membrane experiments. Several computer simulations were performed to demonstrate the success of the system. Simulation results showed that the estimated solute concentration values are very close to the achieved experimental results. The more

Use of Bioballs as an Adsorbent for the Removal of Copper

Nowadays, heavy metals, which are among the various hazardous pollutants, are present at a high level of density in the receiving environments. Among heavy metals, especially copper is mainly present in wastewater due to the industrial activities. Adsorption is the most practical method to prevent this pollution, and in recent years, researchers have been involved in researching both adsorption and cost-efficient, accessible, easy-to-apply environmentally friendly adsorbents. In this study, the adsorption capacity of high density bioballs having a potential adsorbent characteristic was more

One-Pot Fabrication of K-Doped g-C3N4/SiO2Composite with Enhanced Photocatalytic Activity for Degradation of Tetracycline

K-doped g-C3N4/SiO2composite (SiO2/K-CN) was synthesized by a facile thermal polymerization with potassium chloride, melamine and nano-silica as raw materials. The as-prepared SiO2/K-CN was characterized by various measures. The photocatalytic activity of SiO2/K-CN was tested via the photocatalytic degradation of tetracycline under visible-light irradiation. The results showed that the specific surface area of SiO2/K-CN catalyst was 28.16m2/g, which is larger than that of pristine K-doped g-C3N4. Both K-doping and silica-combination can reduce the recombination rate of photo-generated more

A Comparative Application of Latin Hypercube Design and Box-Behnken Design Methods in Extracting Sesameoil

In the past decades, most researchers focus on process optimization and extraction methods to improve oil extraction from oilseeds. However, no information available on comparative analysis of different design methods to improve the process. The objective of this study was to evaluate the applicability of Latin hypercube design (LHD) and Box-Behnken Design (BBD) in oil extraction. Experimental oil yield, analysis of variance (ANOVA) of the model, and practical observation were used to compare the methods. The result shows both methods can supply adequate data for experiments. The range of oil more

Study of the Synthesis and Characterization of Poly(acrylic acid-co-acrylamide)-kaolinite Composite Reference to Adsorption of Cd and Pb from Aqueous Solutions

A novel poly(acrylic acid-co-acrylamide)/ kaolinite composite was produced by copolymerization of partially neutralized acrylic acid and acrylamide with sawdust for crosslinking applying Bis-acrylamide having linear formulae (C₇H₁₀N₂O₂.), (H₂C=CHCONH) 2CH₂, potassium persulfate, K2S2O8 as initiator and sodium sulphite used as accelerator to reduce the polymerization time. Physiognomy of the composite was performed by techniques viz., Fourier Transform Infrared Spectroscopy, X-Radiation Diffractometry (Crystallography), Structural-Equation-Modeling, Energy-Dispersal X-Radiation-Analysis and more

DOX-Loaded Gelatin Composite Hydrogels with Oxidation-Triggered Drug Release Property

Hydrogels developed as stimuli-responsive drug delivery systems (DDSs) are increasingly concerned research focus in many fields such as chemistry, functional materials and biomedicine. Herein, we report the fabrication, characterization and drug release property of new gelatin composite hydrogels by using biocompatible gelatin and the doxorubicin (DOX)-loaded micelles of a redox-responsive side-chain ferrocene (Fc)-containing amphiphilic diblock copolymer PNFc-b-PNTEG (Fig. 1). The self-assembly method was firstly adopted to prepare the DOX-loaded micelles of PNFc-b-PNTEG with more

Influence of Industrial Processing on Physiochemical Characteristics of Soybean Oil and Deodorizer Distillates

The present study aimed to evaluate the impact of industrial processing (neutralization/degumming, bleaching, and deodorization) on physicochemical characteristics of soybean oil and soybean oil deodorizer distillate (SBO-DD) collected from two different industries. The substantial impact of processing was observed on all physicochemical parameters except the iodine value (IV) and saponification value (SV). Gas chromatography-flame ionization detector (GC-FID) and Gas chromatography-mass spectrometry (GC-MS) analytical techniques were used for the quantification of individual fatty acids, more

Synthesis, Characterization and TheoreticalStudies of N'-(4-methoxybenzylidene)benzenesulfonohydrazide

N'-(4-methoxybenzylidene)benzenesulfonohydrazide was synthesized and elemental analysis was conducted; IR, Raman, 1H, and 13C NMR spectral data were recorded. The potential energy surfaces (PES) of the N'-(4-methoxybenzylidene)benzenesulfonohydrazide molecule were obtained by selected degree of torsional freedom, which varied from 0o to 360º in 4º increments. The conformers were optimized by using a (DFT/B3LYP/6-31G(d,p)) basis set in the gas phase. The eleven conformers in the gas phase of the obtained molecule were determined and the most stable conformer (conformer 1) was re-optimized by more
