✦ Synopsis

Ah&met A computer method for the treatment of kmetlc data prowded by a diode-array spectrophotometer was developed The method rebes on a non-lmear regresaon procedure for estlmatmg the rate constants and concentrations of nuxture components The underlymg prmclple of dus method 1s fitting the absorption matrtx obtamed as a function of tune and wa~len~h to a theoretical kmebc equation Ths allows the resolution of matures of compounds w& sundar rate asps m a sumdtaneous fashion prowded that they or their reactmn products feature apprecxable spectral dxfferences from one another The proposed method was apphed to the resolution of C&I) (0 l-l 0 pg ml-')-N&I) (0 S-5 0 fig ml-") &ures based on displacement from thetr the EGTA complexes by 4_(2'-pyrtdyhxzo)resorcmoi B Kmeta methods, UV-Vlslble spectrophotometry, Cobalt, Computer fittmg, Nickel
