Abstract

Abstract: The application of the PLS method to simultaneous spectrophotometric determination ofcopper, zinc and manganese in 5-Br-PADAP-OP system has been investigated. The methodgave satisfatory results for the determination of these elements in composite samples and inAl-alloy sample without previous separation. The relative errors are 1.3-9.7%.

Key words: partial least square method, copper, zine, manganese, spectrophotometry simultaneous deter mination
