One-Point Cellulose Adsorbents for Water Purification

Novel chitosan-cellulose hydrogel adsorbents for lead adsorption

In this study, we examined the properties of chitosan-cellulose hydrogel beads as an adsorbent and its application for lead ion adsorption. Chitosan was blended with cellulose to improve the mechanical strength of chitosan hydrogel beads and the chitosan-cellulose hydrogel beads were cross-linked with ethylene glycol diglycidyl ether (EGDE) to enhance their acid-resistant ability. Scanning elec...

Utility of adsorbents in the purification of drinking water: a review of characterization, efficiency and safety evaluation of various adsorbents.

Clean drinking water is one of the implicit requisites fora healthy human population. However the growing industrialization and extensive use of chemicals for various concerns, has increased the burden of unwanted pollutants in the drinking water of developing countries like India. The entry of potentially hazardous substances into the biota has been magnifying day by day. In the absence of a p...

Combining Adsorbents with Membranes for Water Treatment

OBJECTIVES: The primary objective of this project was to evaluate the feasibility of using heated iron oxide particles (HIOPs) in conjunction with various types of membranes to enhance natural organic matter (NOM) removal and reduce fouling of those membranes. Secondary objectives were to compare the behavior of HIOPs with that of powdered activated carbon (PAC) as additives to UF systems, and ...

New generation adsorbents for water treatment.

New Adsorbents for Purification: Selective Removal of Aromatics

Adsorption of benzene and cyclohexane on ®arious Y-zeolites was in®estigated to de®elop sorbents for the purification of aliphatics by remo®al of aromatics. Ag-Y showed superior benzenercyclohexane selecti®ities to Na-Y, Pd-Y, and H-USY. Separation factors greater than 10 5 were obtained with Ag-Y at low concentrations of benzene. High selecti®ities were achie®ed by the strong interaction betwe...
