摘　　要：含锌硝酸铵钙为四川泸天化股份有限公司硝酸铵的改性产品,即硝酸铵中添加了钙、镁、锌元素。通过试验建立了含锌硝酸铵钙产品中锌、镁含量的测定方法,确定了锌含量测定的实验室允许差。本方法精密度、准确度都比较高,锌、镁含量测定的标准偏差分别为0.01和0.10,加标回收率分别为96.00%～106.18%、95.48%～101.72%。The zinc contained calcium ammonium nitrate is one kind of modified ammonium nitrate product that is obtained by adding calcium, magnesium, zinc into the ammonium nitrate. The method for zinc and magnesium determination was found out by examination, with which the test tolerance for zinc determination in lab condition was confirmed. The data＇s precision and accuracy by this method are high, the standard deviation for zinc and magnesium test are 0.01 and 0.10, the recovery rates are 96.00% - 106.18% and 95.48% - 101.72%.
