碘离子电极在测定岩石、土壤、盐卤中的碘含量已有报导。应用卤素离子电极测定感光材料中的卤素比也取得了成功。本文系统研究了碘离子电极在感光材料分析中各种照相物质对碘离子电极测定的影响因素,从而找到了最佳测试AgX乳剂中的碘含量,实测了各种乳剂中的碘含量。并进一步研究了应用碘离子电极测定了照相有机物中的碘含量,其数据与电位滴定法相对照两者颇为吻合,有推广应用的价值。
Iodide ion electrode in the determination of rock, soil, salt brine iodine content has been reported. Halogen ratios in photographic materials have also been successfully measured using halogen ion electrodes. In this paper, we systematically studied the influencing factors of iodine ion electrode determination of various photographic materials in iodine ion sensitive material analysis, so as to find the best iodine content in AgX emulsion and iodine content in various emulsions. The iodine content in photographic organics was also determined by iodide ion electrode. The data of iodine ion in the photographic organism is quite consistent with that of the potentiometric titration method, which has the value of popularization and application.
