| Abstract: | 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%. |
