- •
SSMA microspheres were prepared from poly(styrene-alt-maleic anhydride) by sulfonation reaction.
- •
The presence of −SO3H on the surface of SSMA made it a possible candidate for the adsorption of positively charged dyes.
- •
SSMA was an absorbent for selective removal of cationic dyes.
- •
The adsorption capacity of SSMA for cationic dyes was greatly increased compared to that of SMA.
