其他信息

  • 可燃性危险特性:不燃
  • 使用限量:FAO/WHO(1984)：加工干酪(9g/kg，总磷酸盐量，以磷计)。
  • 参考质量标准:FAO/WHO，1992 含量 ≥96.0% 灼烧失重(800～825℃，30min，试样lg) ≤1.5% 氟化物(GT-15)450mg kg 砷(以As计) ≤3mg/kg 铅 ≤10mg/kg 重金属(以Pb计) ≤30mg/kg
  • 含量分析:精确称取试样约200mg，溶于10ml稀盐酸试液(TS-117)中。加约120ml水，冷却30min，在冷却期间按需要添加稀盐酸或水，使溶液的体积和Ph值保持恒定。冷却后加0.05mol/LEDTA二钠25ml，用水稀释至200ml。用强氨试液(TS-14)中和。加10ml缓冲液(PH 10；TS-12)和铬黑试液(TS-97)数滴。用0.05mol/L硫酸锌滴定。每Ml 0.05mol/L EDTA二钠相当于焦磷酸钙(Ca2P207)6.352mg。
  • 类别:有毒物质
  • 鉴别试验:溶解性 不溶于水；溶于稀盐酸和稀硝酸。按OT-42方法测定。 取1%试样的稀盐酸试液(TS-117)的溶液lml，加硝酸银试液(TS-210)数滴。应产生能溶于稀硝酸试液(TS-158)的白色沉淀。 取试样约100mg，加稀盐酸试液5ml和水5ml，温热溶解，滴加氨试液(TS-13)2．5ml，伴以振摇，再加5ml草酸铵试液(TS-24)。应生成白色沉淀。
