Alginate/Ni-Al-layered double hydroxide/dye (Alg/Ni-Al-LDH/dye) composite films were fabricated using the solution casting method. The dyes used included methyl red, phenol thymol blue, bromothymol m-cresol purple, orange, bromocresol purple (BP), and green (BG) in overall pH range of 3.8 to 9.6. chemical composition morphology Alg/Ni-Al-LDH/dye film structure investigated by Fourier transform infrared spectroscopy, FESEM, atomic force microscopy, X-ray diffraction. semitransparent...
Abstract A new application of hybrid emulsion liquid membrane, in which an O/W phase is placed between two supporting membranes, applied the present research for removal cadmium from aqueous phase. The setting has advantages such as higher stability phase, lower pollution feed and stripping phases due to contacting with membrane capacity. Trioctylamine been used a carrier organic emulsion, while surfactant nonyl phenol ethoxylate. effect different parameters investigated, pHs dispersed...
A hybrid liquid membrane process was used to remove cadmium cation from a solution using bis-(2-ethylhexyl) phosphoric acid as the carrier for first time. Different polyethersulphone supporting membranes were prepared by phase inversion technique. The could be efficiently proposed process. effects of porosity and pore size on removal efficiency investigated. In addition, various operating parameters such concentration in organic phase, pH feed concentration, temperature performance also It...
Liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. In this study, a modified hybrid liquid system is introduced. The setup worked by applying the water-insoluble dioctyl phthalate organic solvent. N-octanol and tetra butyl ammonium bromide are added to phase increase efficiency. effects different parameters pHs feed stripping phases, complexing agent concentration, film thickness, initial...
Abstract Demands for phosphoric acid are growing rapidly in various industries. This has highlighted the importance of optimizing its production and purification methods. Phosphoric can be produced by a wet process. However, due to presence many organic inorganic impurities product, resulting product is major concern this industry. Removal trace metal (such as magnesium, cadmium, chromium, zinc, etc .) from process was investigated foam fractionation semi‐batch setup using sodium dodecyl...
