聚合氯化铝(Polyalumium Chloride)又称羟基氯化铝,碱式氯化铝,是由氯化铝和氢氧化钠在一定条件下制成的淡黄色粒状固体,分子式为(Al_2(OH)_nCl_(6-n)]m,作为新型的絮凝剂,应用于饮水净化处理,具有经济、高效、取材丰富、综合利用等优点。聚合氯化铝的毒性很低,按毒性分类属于基本无毒(LD_(50)雄性小鼠5201mg/kg,雌性小鼠4854mg/kg)。关于聚合氯化铝的毒性研究甚少,1978年苏联А.А.Коррпев研究了羟基氯化铝在饮水中的残留标准,根据味觉阈作为限制指标,建议其在饮水中的最大残留量为1.5mg/l。日本规定了聚合氯化铝的产品标准。鉴于聚合氯化铝本
Poly aluminum chloride (Polyalumium Chloride), also known as aluminum hydroxychloride, basic aluminum chloride, aluminum chloride and sodium hydroxide is made under certain conditions by the light yellow granular solid, molecular formula (Al 2 (OH) _nCl_ (6-n)] m, as a new type of flocculant, is applied to the purification of drinking water and has the advantages of economy, high efficiency, rich harvesting, comprehensive utilization, etc. The toxicity of polyaluminum chloride is very low, LD 50 male mice 5201 mg / kg and female mice 4854 mg / kg.) Little is known about the toxicity of polyaluminum chlorides. In 1978 Soviet Union А.А.Коррпев studied the residual standards of aluminum hydroxychloride in drinking water , According to the taste threshold as a limit indicator, it is recommended that the maximum residue in drinking water is 1.5mg / l Japan provides the product standard of polyaluminum chloride In view of the polyaluminum chloride
