| Abstract: | This paper presents a method for the spectrophotometric determination of iodine in soil by starch coloration. The method is simple, convenient, rapid, accurate and easy to be mastered. The average recovery of the method is 100.5%, the standard deviation 0.30 mg kg~(-1) and the coefficient of variation 4.8% (n=5). |
