Evaluation of ion exchange material from sulfonated polystyrene waste synthesized for removal Cr3+ from aqueous solution by column experiment

Removal of Copper from Aqueous Solution by Ion Exchange Resins

Nanofiltration Membranes Synthesized from Polyethyleneimine for Removal of MgSO4 from Aqueous Solution (RESEARCH NOTE)

A novel work was performed for fabrication and modification of composite nanofiltration (NF) membrane by polymerization reaction between polyethyleneimine (PEI) and triphthaloyldechloride (TPC). the main purpose of this work was water treatment. polysulfone was applied as a main polymer of substrate. The result of reaction between PEI and TPC would be formation of polyamide layer on the membran...

Removal of Pb (II) Ion and Safranin Dye from Aqueous Solution by Sheep Wool

The ability of sheep wool to remove Pb(II) ions and safranin dye from aqueous solutions through the adsorption process was investigated at room temperature. The metal ions concentration was determined by flame atomic absorption spectrophotometer method. The influence of pH, contact time, amount of adsorbent, temperature and initial metal...

Use of Agricultural Waste for Removal of Cr(VI) from Aqueous Solution

Evaluation of Cr (VI) ion removal from aqueous solution by bio-inspired chitosan-clay composite: Kinetics and isotherms

This paper reports the evaluation of adsorbing Cr (VI) ions on sorbent prepared from chitosan (CHT), a versatile derivative of chitin, and dodecyl amine modified locally available kaolinite clay (Bijoypur clay) (MC) that has excellent mechanical properties and great resistance to chemical and biological attack. The effect of the initial metal ion concentration, solution pH, contact time, and ad...
