水是生命之源,严格监测水中有害金属是保障人们身体健康的有力措施之一。纯净水国家卫生标准规定铅≤001ｍｇ/Ｌ,锌、铜≤005ｍｇ/Ｌ[1]及生活饮用水输配水设备及防护材料的安全性评价标准铅≤0005ｍｇ/Ｌ,其含量很低,难以用火焰原子吸收法直接测定。我国国家卫生标准对此类痕 Water is the source of life. Strict monitoring of harmful metals in water is one of the powerful measures to protect people’s health. Pure water national health standards lead ≤ 001mg / L, zinc, copper ≤ 500mg / L [1] and drinking water distribution equipment and protective materials safety evaluation standard lead ≤ 5000mg / L, its content is very low, it is difficult Direct determination by flame atomic absorption spectrometry. China’s national health standards on such marks
