锰、锌和铁是人体不可缺少的微量元素,所需主要来源于食物和饮用水。但饮用水中含量过高,不仅影响饮用水的感官和口感,也会造成人体消化系统,神经系统的损害。目前测定生活饮用水中锰、锌和铁的方法有原子吸收分光光度法,包括直接法、共沉淀法、萃取法、富集法,不同显色剂的分光光度法,ICP法等[1]。由于原子吸收分光光度法直接法锰、铁不符合卫生标准评价要求,浓缩法和分光光度法操作相对繁琐,ICP法仪器设备昂贵;
Manganese, zinc and iron are indispensable trace elements in the human body, mainly from food and drinking water. But drinking water is too high, not only affects the senses and mouthfeel of drinking water, but also causes the human digestive system and nervous system damage. At present, the methods for the determination of manganese, zinc and iron in drinking water are atomic absorption spectrophotometry including direct method, coprecipitation method, extraction method, enrichment method, spectrophotometry with different chromogenic agents, ICP method [1] . As the atomic absorption spectrophotometry direct method of manganese, iron does not meet the health standards evaluation requirements, concentration and spectrophotometry is relatively complicated operation, ICP method equipment expensive;
