The concentration of polyacrylamides is determined by precipitation with Hyamine 1622 Reagent 1 and by measurement of the amount of light scattered by the resulting turbidity. The analysis can be automated as well as adapted for field trials. The effects of anionic surfactants, changes in polyacrylamide molecular weight, and salinity are discussed.

Can anionic microblocks improve the flocculation performance of high turbidity water?

Flocculation experimental results demonstrated that the anionic microblocks in the template copolymer could enhance the charge neutralization and bridging ability, and therefore an excellent flocculation performance of treating high turbidity water was observed. 1. Introduction

Can UV-initiated template polymerization prepare a novel anionic polyacrylamide with a microblock structure?

E-mail: zhl6512@126.com; Fax: +86 23 65120827; Tel: +86 23 65120827 Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure.

Does UV-initiated polymerization produce a new anionic flocculant TPAs with a microblock structure?

Conclusions A new anionic flocculant TPAS with the microblock structure was successfully synthesized through UV-initiated polymerization. The structure properties of TPAS was characterized by the FT-IR, 1H (13C) NMR, SEM and TG/DSC, and the results indicated that the formation of the microblock structure.
