What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (Anionic PAM, APAM) Structure and properties: Anionic PAM is a water-soluble polymer. By introducing these anionic groups on the polymer backbone, APAM can react with positively charged substances. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.

What are the adsorption properties of Pam polymers?

The polymer’s adsorption properties in dependence on the following parameters solution pH (in the range 3–9), temperature (in the range 15–35 °C), and carboxyl groups’ content in the PAM chains (in the range 5–30 %) were examined. The turbidimetry method was applied for determination of the suspension stability of alumina in the presence of PAM.

Does anionic polyacrylamide increase stability of dispersed solid particles?

Generally, the anionic polyacrylamide addition improves stability of the dispersed solid particles (at fixed pH and temperature, the decrease of TSI values for the system containing PAM in relation to that without polymer is observed). Table 2. Stability coefficient TSI for all examined systems, C PAM = 100 ppm

What is ionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.

What are the different types of polyacrylamide (PAM)?

According to its ionic properties, PAM is divided into three main types: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) and nonionic (Nonionic PAM, NPAM). These three types have significant differences in structure, function and application. 1. Cationic polyacrylamide (Cationic PAM, CPAM) Structure and properties:

What is nonionic polyacrylamide?

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.
