EDTA溶液萃取硝酸磷肥中枸溶性磷的试验

The Experiment on Extracting Citrate Soluble Phosphate of Nitrophosphate Fertilizer by EDTA Solution

分别用EDTA溶液和中性柠檬酸铵溶液萃取并测定硝酸磷肥中枸溶性磷含量,提出了EDTA萃取剂替代中性柠檬酸铵萃取剂的可行性。

We extract citrate soluble phosphate from nitrophosphate fertilizer by EDTA solution and neutral ammonium citrate respectively then assay it. This method expound a feasibility that neutral ammonium citrate as a extractant can be superseded by EDTA solution in the process.
