Abstract

This experiment was conducted to improve the analytical method of tricyclazole- and IBP-combined dust. When the tricyclazole and IBP active ingadients were analyzed by the official analytical method, their recovery rates were 89.5 and 100%, respectively. A reason of the lower recovery rate in tricyclazole was found to be due to strong binding to the minor inorganic compoments, $Al_2O_3$, $Fe_2O_3$, CaO and MgO, of talc and kaoline. However, addition of 0.2% dimethylamine to extraction solvent for tricyclazole- and IBP-combined dust effectively raised the recovery rate of tricyclazole by providing higher basicity than tricyclazole. We have suggest an improved analytical method which is applicable to effective and simultaneous analysis of the active ingradients of tricyclazole- and IBP-combined dust.
