从氯铵T-四碱体系测定碘量的反应机理入手,对影响该体系测定土壤中碘量稳定性的因素进行了研究。研究表明,通过加入抗坏血酸可以获得较好的测定稳定性。
Starting from the reaction mechanism of determination of iodine in ammonium chloride T-tetra-alkali system, the factors that affect the stability of iodine in soil were studied. Studies have shown that good assay stability can be achieved by adding ascorbic acid.
