    • Composition and method of use for tannin based environmentally benign polymeric coagulants are disclosed. Tannin based coagulants are copolymers of naturally occurring tannins and a cationic monomer. One embodiment of the present invention provides for a composition, of a tannin based polymeric coagulant which is comprised of N,N-(dimethylaminoethyl) methacrylate (MADAME) polymerized using t-butylhydroperoxide and sodium metabisulfite. The resulting polyMADAME is converted to hydrochloride and then blended/reacted in an aqueous medium with tannin to obtain a homogenous poly(MADAME)-tannin composition. The method of use comprises adding an amount of the composition effective for the purpose of clarifying oily wastewater from food and beverage, steel, automotive, transportation, refinery, pharmaceutical, metals, paper and pulp, chemical processing and hydrocarbon processing industries.
    • 公开了用于单宁的环境友好聚合物凝结剂的组合物和使用方法。 单宁絮凝剂是天然单宁和阳离子单体的共聚物。 本发明的一个实施方案提供了由使用叔丁基过氧化氢和偏亚硫酸氢钠聚合的N,N-(二甲基氨基乙基)甲基丙烯酸酯(MADAME)组成的单宁基聚合物凝结剂的组合物。 将所得的聚甲基丙烯酸甲酯转化为盐酸盐,然后在水性介质中与单宁混合/反应,得到均匀的聚(MADAME) - 鞣酸组合物。 使用方法包括添加一定量的组合物,用于澄清食品和饮料,钢铁,汽车,运输,炼油,制药,金属,造纸和纸浆,化学加工和烃类加工业中的油性废水。
