Heavy metals and dyes are major pollutants that pose potential threat to the health of humans and ecosystems. Various technologies are available to remediate such pollution, but these processes are costly, have high energy requirements and generate toxic sludges and wastes that need to be carefully disposed. There is therefore a need for methods that are more efficient, cost effective and environment...
Adsorption of dyes via strong interactions between modified cellulose paper and dyes is an economical, effective, and sustainable method for treating wastewater. In this work, using multiple interactions with dye molecules, an imidazolium ionic liquid modified cellulose adsorbent (CCP-Im) was prepared and used to treat anionic dye wastewater effectively. Zeta potential tests and Gaussian simulations...
The surface modification of cellulose fabric with chitosan was achieved through an oxidation of the fabric with KIO4 followed by reductive ammination with chitosan. The chitosan content in the fabric determined by Kjeldahl nitrogen analysis technique was 1.69%. The scanning electron micrograph revealed submicron particles of chitosan attached on the fabric surface. Dyeing of the modified fabrics with...
