| Abstract: | The exchangeable iron in soil was determined by spectrophotometer method.The conditions that effected the extraction efficiency were investigated,including the concentration of extraction solution,pH value and extraction time.The results indicated that the level of the exchangeable iron in soil was ranged from 0.096 to 0.116 g/g with the spiked recovery ranging 98.9%~100.4%. |
