本文报导了用Ni——二甲酚澄——溴化十六烷基三甲基铵三元络合物快速测定镍的反应条件和络合物的组成,方法具有灵敏度高,选择性好等优点,最大的特点是显色较迅速,颜色稳定。并提出了用柠檬酸钠——磷酸三钠作为Fe~(+++)、Al~(+++)Cr~(+++)、Co~(++)、Pb~(++)等离子的掩蔽剂,制定了不经分离,快速测定土壤中微量镍的新方法。 This paper reports the rapid determination of the nickel reaction conditions and the composition of complexes by Ni-xylenol chelate-cetyltrimethylammonium bromide ternary complex. The method has the advantages of high sensitivity and good selectivity Advantages, the biggest characteristic is more rapid color development, color stability. And proposed the use of sodium citrate - trisodium phosphate as Fe ~ (+++), Al ~ (+++) Cr ~ (+++), Co ~ (++), Pb ~ (++) Of the masking agent, developed without separation, rapid determination of trace amounts of nickel in soil method.
