Based on current industry principles and research, when using an anionic organic polymer flocculant like SMAS (Sodium Methallyl Sulfonate) copolymer…

Sodium Methallyl Sulfonate (SMAS) copolymer cannot be dosed simultaneously with aluminum/iron inorganic coagulants.Metal ions (Al3+/Fe3+) readily coordinate with anionic -SO3– from SMAS,…

SMAS-based flocculants perform better than common PAM for negatively charged fine coal slime in coal washing wastewater.

1. Reasons for aqueous/precipitation polymerization of Sodium Methallyl Sulfonate (SMAS) 2. Negative impacts under overly acidic pH Excess acid protonates…

Carboxylate groups lose ionization and shrink in high-salinity brine due to cation shielding, while sulfonate on Sodium Methallyl Sulfonate (SMAS)…

1. Cationic monomer example: DAC (Acryloyloxyethyl Trimethyl Ammonium Chloride) Sodium Methallyl Sulfonate (SMAS) copolymerizes with DAC. Positively charged DAC captures…

Functional Roles of Groups in Sodium Methallyl Sulfonate (SMAS) 1. Carbon-carbon double bond (C=C) The reactive vinyl double bond enables…

Core Reasons 1. Diversified copolymerization capability SMAS can copolymerize easily with acrylamide, acrylic acid, maleic anhydride and other common monomers…
