Adsorptive features of chitosan entrapped in polyacrylamide hydrogel for Pb2+, UO22+, and Th4+
(ELSEVIER SCIENCE BV, 2008)
Chitosan (Ch) was entrapped in polyacrylamide (PAA) by direct polymerization of acrylamide in a suspension of Ch. The adsorptive features of PAA-Ch and Ch were then investigated for pb(2+), UO22+, and Th4+ in view of ...
Lead removal by polyacrylamide-bentonite and zeolite composites: Effect of phytic acid immobilization
(ELSEVIER SCIENCE BV, 2005)
Polyacrylamide (PAA)-bentonite (B) and zeolite (Z) composites were prepared by direct polymerization of PAA in suspensions of B and Z. Phytate (Phy) immobilized onto the composites to obtain their Phy modifications. FT-IR ...
