The article introduces determination of iron content in soil or sediment by sulfosal incylic acid spectrophotometric method. A new method for the determination of iron content in soil or sediment by HCI-HNO3 acid dissolution, sulfosal icylic acid spectrophotometric method was developed. The analysis approache was established.This method is simple, sensitive, and has good selectivity and less environmental contamination. The satisfactory results were obtained. The results of testing the standard samples indicated that this method is reliable and the accuracy is suitable. The course of experimental methods was introduced detailed, and the actual work has some guidance significance.
