【Abstract】 In this paper the experiments of salt floccularion and solvent flocculation on the gelatin and their succinylation are studied. The influence of pH value on flocculation, as well as the amount of salt required for the flocculation, is investigated. Contrary to those flocculated by solvents, the succinylated gelatin is more easily flocculated by salt than the gelatin does.更多还原
