我们用氟离子选择电极法(以下简称电极法)和原来的蒸馏后的硝酸钍容量法(以下简称容量法)对磷矿、沉淀磷酸钙饲料、黄磷电除尘渣、黄磷污水、磷酸等试样中的氟含量进行了对照测定,并对电解铝厂的空气、地面水、土壤、植物(稻壳、唐菖莆及野生中草药旋复花、石荠苧、旱莲草、丁香蓼、车前草等)、人尿等进行了五百多个样品的测定,获得了满意的结果。
We use fluoride ion selective electrode method (hereinafter referred to as the electrode method) and the original method of thorium nitrate volumetric distillation (hereinafter referred to as volume method) on phosphate rock, precipitated calcium phosphate feed, yellow phosphorus ESP, yellow phosphorus sewage, phosphoric acid The content of fluoride in the sample was measured in the control. The effects of air, surface water, soil, plant (rice husk, Tangguopu and wild Chinese herbal medicine Cyperus rotundus, Lithospermum hemlockii, Eclipta prostrata, Polygonum capitatum, Plantain, etc.), human urine, etc. were more than five hundred samples were measured, and obtained satisfactory results.
