Anionic polyacrylamide alleviates cadmium inhibition on

The WAS used in the following AD was from a secondary sedimentation tank of a municipal wastewater treatment plant in Changsha, China, where no PAM-based wastewater treatment was carried out. The background Cd concentration detected in untreated sludge was 0.11 ¡À 0.02 mg L ?1. The collected fresh sludge was filtered through a 0.45-mm

Fabricating an anionic polyacrylamide (APAM) with an anionic

Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template.

Comparative study of anion polyacrylamide (APAM) adsorption

Water-soluble polymers, such as partially hydrolyzed polyacrylamide especially anion polyacrylamide (APAM), one added to the flooding water to improve oil mobility and recovery [2]. Nearly 50-million tons [3] of oilfield-produced wastewater containing APAM, oil, water and sludge are generated every year in China.

Experimental investigations on the physico-mechanical

The typical characteristics of loess, such as macropores, weak cementation, and strong collapsibility, can adversely affect the stability of building foundations, transportation infrastructure, and other geotechnical systems. To address this problem, a water-soluble anionic polyacrylamide (APAM) was used to improve the characteristics of loess.
