Adsorption of cationic polyacrylamide (C-PAM) on expanded
The adsorption of cationic polyacrylamide (C-PAM) onto expanded perlite (EP) from aqueous solutions was investigated as a function of some parameters such as pH, ionic strength, and temperature. The adsorption of C-PAM was increased with increasing pH and temperature and with decreasing ionic strength.
Adsorption of Nitrate Ions onto Sepiolite and Surfactant-modified Sepiolite 327 are magnesium and silicon metal oxides, and they generate positive or negative charges, respec-tively, on the sepiolite surface. The extent of such charge generation is proportional to the pH of the aqueous solution surrounding the oxide particles.

Adsorption of cationic, anionic and hydrophobically
The adsorption of modified polyacrylamides (PAM) at the silica surface has been studied by ellipsometry. To study the influence of the type of modification of the polyacrylamide on the adsorption behaviour, we have used cationic, anionic and hydrophobically modified polyacrylamides with varying charge density and degree of hydrophobisation.
The adsorption of the cationic polymer, polyacrylamide (PAM), onto kaolinite was investigated. Polyacrylamides are among the most commonly used polymers in industry and adsorption of PAM onto kaolinite from aqueous solutions have been investigated systematically as a function of some parameters such as calcination temperature of kaolinite, pH, ionic strength and temperature.

Enhanced and Selective Adsorption of Mercury Ions
Enhanced and selective removal of mercury ions was achieved with chitosan beads grafted with polyacrylamide (chitosan-g-polyacrylamide) via surface-initiated atom transfer radical polymerization (ATRP). The chitosan-g-polyacrylamide beads were found to have significantly greater adsorption capacities and faster adsorption kinetics for mercury ions than the chitosan beads.

Efficient Removal of Anionic and Cationic Dyes from an
A pullulan-graft-polyacrylamide porous hydrogel was prepared by radical polymerization in the presence of a crosslinking agent (N,N′-methylenebisacrylamide). Then, the swelling behavior of the hydrogel and the kinetics of swelling were investigated. The novel synthesized hydrogel was used as an adsorbent for removal of dyes from aqueous solutions.

- What is reverse osmosis in water treatment & desalination?
- 1. Introduction Reverse osmosis (RO) is gaining worldwide acceptance in both water treatment and desalination applications. It is a pressure-driven process whereby a semi-permeable membrane rejects dissolved constituents present in the feed water.
- What is reverse osmosis (RO)?
- ( Elsevier Ltd. ) Reverse osmosis (RO) conc. samples were obtained from a RO-membrane system that uses effluents of wastewater treatment plants (WWTP) as feed water for the prodn. of drinking water.
- Are reverse osmosis membranes harmful?
- ACS Environ. Au ABSTRACT: As more cities experience water stress, the use of reverse osmosis (RO) membranes for wastewater treatment and reuse will expand. The concentrated waste stream resulting from RO treatment can pose chronic ecotoxicity risks if discharged to surface waters or shallow coastal ecosystems.
- What is reverse osmosis treatment of municipal wastewater effluent?
- ( American Chemical Society ) Reverse osmosis (RO) treatment of municipal wastewater effluent is becoming more common as water reuse is implemented in water-stressed regions. Where RO conc. is discharged with limited diln., concns. of trace org. contaminants could pose risks to aquatic ecosystems.
