%X The interaction of sulfate with various PACl was investigated by using Ferron assay,chemical analysis and SEM.The experimental results showed that the basicity (B=OH]/Al]) exhibited significant role in the PACl-sulfate reaction.It indicated different species in various PACl under different reaction pathway with sulfate.The Alc formed precipitation quickly with sulfate,while Alb underwent slowly crystallization.The decrease of Ala resulted in the limit of ferron method.The different speciation component in PACls formed different crystal morphology and chemical composition with sulfate.Increase the basicity,the content of sulfate in precipitate decreased from 0.45 to 0.30.
