摘要: The absorption and electrokinetic characteristics of alumina suspensions in the presence polyacrylic acid as a dispersant have been studied. adsorption isotherms exhibit high-affinity Langmuirian behaviour. density decreases with increasing pH, while it increases molecular weight polymer. Electrokinetic studies indicate specific at above isoelectric point sample. Possible mechanisms interaction between are discussed.
