Abstract

Influence of hydroxymethylated reaction in different conditions on complexing capacity of sodium lignosulfonate (SL) with Cu( ), Zn( ) and Mg( ) was investigated. By single factor experiment, the optimal reaction conditions were as follows: dosage of formaldehyde was 0.22 g (g SL)-1, temperature was 60~70 , pH was 11.0. Under the optimum condition, the amount of complexed Cu, Zn and Mg of hydroxymethylated sodium lignosulfonate (HSL) increased by 34.9%, 23.3% and 18.9% respectively, compared to the original SL. Moreover, the total hydroxyl group content of SL increased after reaction, which suggested that the main contributor to complexing capacity improvement was total hydroxyl content.
