主　　题：Environmental analytical chemistry chromium (VI) ion diphenylcarbazide UV-visible spectroscopy Tama River. 

摘      要：Compounds containing Cr （VI） ion are widely used for chemical industry, paints, dyes, and other applications. Because of commonly known toxicity of Cr （VI） ion, Cr （VI） is one of the important check items for quality of water in natural river or industrial waste water. Although the only method for selective detection for Cr （VI） ion is diphenylcarbazide, of which pretreatment spends long time according to the regulat^ons by the Ministry of Environment, Japan. Herein we develop a new and simple pretreatment for the job site and suitable for education and attempt to apply for analysis of the soil in Tama River actually.
