摘要
提出用微波干燥法测定过磷酸钙中水分的含量,测定的精密度较高,操作简便,条件容易控制,分析速度快,RSD=(n=6)为1.23%。经多次试验证明,采用本法测定结果满意。
Micro-wave drying method, which is used to determine the water content in single superphosphate, is characterized by high-leveled precision, simple operation, easy-controlled operating conditions, and fast analyzing speed with RSD=（n=6） 1.23%. Repeated experiments have made it clean that the test results are satisfactory when microwave-drying method is adopted.
