摘要： Provided a method for treating hardly-decomposable-substance-containing water, in which hardly decomposable substances such as dioxins, contained in contaminated water (treatment raw water) are concentrated and rendered harmless by providing the steps of (B) adding an adsorbent to water containing a hardly decomposable substance (treatment raw water) to cause the hardly decomposable substance to be adsorbed on the adsorbent (adsorption treatment step), (C) separating a permeated liquid through a filter membrane to concentrate the adsorbent adsorbing the hardly decomposable substance (membrane filtering treatment step), and (D) chemically decomposing the hardly decomposable substance adsorbed on the concentrated adsorbent with a peroxide without any operation of desorption from the adsorbent (chemical decomposition step), and the method can be applied to water containing a reducing substance such as bisulfate that neutralize free chlorine and can render the hardly decomposable substances harmless efficiently at a low cost without being limited by properties of the hardly decomposable substances contained.

摘要： A triazine derivative, a herbicide containing the same as an effective ingredient and the production of said derivative represented by general formula (I) or (II), [wherein X1 represents H, an alkyl, alkoxy or alkylthio group each having 1-4 carbon atoms, and alkyl, alkoxy or alkylthio group each having 1-4 carbon atoms and substituted by halogen, or a halogen atom, n represents an integer of 1-4, Z represents O or S, R1 represents a C1-C4 alkyl group, R2 represents a C1-C4 alkyl group substituted by halogen and R3 represents NH2, NHCOR4 or N=CHR5 (wherein R4 represents H, a C1-C4 alkyl group, a C1-C4 substituted alkyl group, a C3-C6 cycloalkyl group or a C2-C5 alkenyl group and R5 represents an alkyl, alkoxy or alkylamino group each having 1-4 carbon atoms)]. These compounds are produced by reacting a salt of corresponding benzofuranylalkylamine with cyanoguanidine to prepare a salt of benzofuranylbiguanide and then by reacting it with an ester of the general formula R2 COOR6 (wherein R2 represents a C1-C4 alkyl group substituted by halogen and R6 represents a C1-C4 alkyl group) to prepare a triazine derivative (R3 in the general formulas I, II represents an NH2 group provided that the NH2 group can be changed optionally to other R3).
