    • A wastewater which contains a borofluoric acid salt and is discharged by a plater, glass processor, printed-wiring-board manufacturer, etc. can be made to be extremely easily treated efficiently with an existing apparatus at ordinary temperature in a short time while preventing sludge generation. The wastewater treatment can be attained with a borofluoric acid-trapping agent represented by the following general formula (1) or (2). General formula (1) (1) R1 to R4 each independently represents C1-24 alkyl, alkenyl, phenyl, or benzyl, provided that R1 to R4 may be bonded to one another to form a ring; and X represents an anion. General formula (2) (2) R1 to R4 each independently represents C1-24 alkyl, alkenyl, phenyl, or benzyl, provided that R1 to R4 may be bonded to one another to form a ring; and A represents an anionic polymer.
    • 含有硼氟酸盐的废水可通过普通玻璃处理器,印刷线路板制造商等排出,可以在常温下在短时间内用现有设备进行有效的处理,同时防止污泥 代。 废水处理可以用以下通式(1)或(2)表示的硼氟酸捕集剂来实现。 通式(1)(1)R 1〜R 4各自独立地表示C 1-4烷基,烯基,苯基或苄基,条件是R 1〜R 4可以彼此键合形成环; 而X - 代表阴离子。 通式(2)(2)R1至R4各自独立地表示C1-24烷基,烯基,苯基或苄基,条件是R 1至R 4可以彼此键合形成环; 而A代表阴离子聚合物。
