Effect of cationic polyacrylamide on the seeded agglomeration process of sodium aluminate liquors
Effect of cationic polyacrylamide (PAM) on the seeded agglomeration process of sodium aluminate liquors was investigated, conclusions were drawn as follows. Cationic PAM can
In this study, the flocculation performance and kinetics of magnetic cationic polyacrylamide (MCPAM) microspheres, compared with cationic polyacrylamide (CPAM), were systematically investigated under different magnetic field strengths.

Ionic liquid‐assisted SDS‐PAGE to improve human serum protein separation - Zhang - 2011 - ELECTROPHORESIS - Wiley Online Library
Ionic liquid (IL)‐assisted sodium dodecyl sulfate polyacrylamide gel electrophoresis (ILs‐SDS‐PAGE) was presented to improve protein separation. ILs were employed during the preparation process of polyacrylamide gel, then the modified gel was
where C i is ion concentration (mol L −1) and z i is ion valence. Given the conditions in this example, the electrical double layer thickness is estimated to be 4.8 nm from Equation 5.For nonionic linear polymers, the average radius of gyration
- What are the synthesis parameters of aluminum chloride hexahydrate?
- The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- What is a preformed polyaluminum salt?
- Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
- Does polyaluminum chloride remove colloidal matter from dam water?
- In the present work, a new composite coagulant of the inorganic–organic type, prepared by polyaluminum chloride (PAC) premixed with sodium alginate (SA), was tested to remove colloidal matters from dam water.
