SIMPLE CONCENTRATION MEASURING COMPOSITION AND SIMPLE CONCENTRATION MEASURING METHOD FOR DILUTE FUNGICIDE SOLUTION

摘要

PROBLEM TO BE SOLVED: To easily and quickly measure and control the concentration in a treating vessel of an industrial fungicide, and in particular of a dilute fungicide solution for wood.;SOLUTION: An aqueous solution containing a vanadate as a pretreatment agent and an aqueous solution containing a molybdate as a color-producing agent are used for measuring easily the concentration of the dilute fungicide solution for wood containing a phosphate, and the concentration of the fungicide for wood is determined quickly by comparing colorimetrically coloration using the pretreatment agent and the color-producing agent with coloration of a standard solution color-developed by the same manner, or by measuring an absorbance.;COPYRIGHT: (C)2008,JPO&INPIT
