Abstract

Abstract: Fuzzy cluster has been applied to factor the analysis spectrophotometry for resolving the optimized problem of calibration model. The precision of calculated concentration has been raised apparently,For realizing the process automation of optimizingcalibration model the data-base has been set and the cluster parameters have been selected.Fifteen rare earth elements in geologic samples have been determined by this method. The relative standard deviation for 15 REEs are 0-3.85%, respectively.

Key words: Fuzzy cluster, Factor analysis, Rare earth element, Spectrophotometry
