摘要
为了准确测定油脂特别是毛油中的磷含量 ,参照国标测定植物油中磷含量的方法 ,通过调整称样量和稀释倍数 ,应用钼蓝比色法 ,对国内外不同精炼程度油脂中的磷含量做了测定。结果表明 ,通过调整称样量和稀释倍数 ,可准确测定各种油脂中的磷含量。
In determination of phosphorus content of crude oil by national standard method,the phosphorus content depends on the sample weight.Based on the national standard method,the determination of phosphorus content was studied by colorimetric measurement of phosphorus as molybedenum blue. By adjusting the sample weight or the diluting factor, the correct phosphorus content can be reached.
