Pan, Fu-de published the artcileDetermination of total amount of rare earth elements in tea by arsenazo III-spectrophotometry coupled with extraction with PMBP, Name: 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, the publication is Lihua Jianyan, Huaxue Fence (2016), 52(1), 93-95, database is CAplus.

In the work, the sample was subjected to mixed acid digestion, the test solution was purified by combined masking, extraction, and back extraction methods, and the content of rare earth elements was determined by arsenazo III-spectrophotometry. The results of the method were accurate and reliable. Spectrophotometry had the advantages of simplicity, fastness, low cost, etc., and had the significance of popularization and application.
