Simultaneous Determination of Iron and Antimony with Artificia Neural Network by Kinetic Spectrophotometry

Shen Jinshan, Zhang Xinshen *, Chen Rongyi, Li Shuwei (School of Light Industry and Textile and Foodstuff Engineering, Sichuan University, Chengdu 610065)  
A method for the simultaneous determination of Fe? and Sb by kinetic spectrophotometry was established. Fe? has inductive effect on the reaction of Cr I - as same as Sb . They can be determined separately by the spectrophotometric method that makes use of the reaction of I 2 starch as indicating reaction. Although the determination of Fe? and Sbin a solution will interfere with each other, the synergistic effect was observed and made use of being the basis of the method combined with the advantages of artificial neural network in handling data. The method has been applied to determine simultaneously Fe? and Sb in soil and synthetic sample with satisfactory results.
