In this paper, the conditions of modified melamine-formaldehyde resin (MF) used for a flocculent such as the ratio of reactant,reaction time, reaction temperature and the value of pH, were studied. The preferable synthetic conditions were melamine: formaldehyde:acrylamide (mole) = 1: 5: (2～ 3), reaction temperature 70 ℃, reaction time 4 h, pH 9.0.
