研究了铬-二苯基碳酰二肼反应的性质。比较了铬(VI)、铬(III)、铬(II)离子与二苯卡巴肼和二苯卡巴脲的吸收数据。测定了各种体系的化学计量比，以及pH值和有色反应产物在非水介质中的萃取性的影响。观察了有色络合物在电场作用下的行为。推测了铬与有机试剂反应形成的高吸收络合物的性质。
A study of the nature of the chromium-diphenylcarbazide reaction was carried out. Absorptimetric data for the reac-tions of chromium (VI), chromium (III) and chromium (II) ions with diphenylcarbazide and diphenylcarbazone were com-pared. The stoichiometry of the various systems was determined together with the effects of pH and the extraetability of the colored reaction product into non-aqueous media. The behavior of the colored complex under the influence of an electric field was observed. The nature of the highly absorbing complex formed in the reaction of chromium and the organic re-agents was postulated.
