Abstract

Odpadná kyselina chlorovodíková z výroby aktivovaného bentonitu obsahuje ako nečistoty hlinité, železnaté, vápenaté, horečnaté, sodné a draselné ióny. Na neutralizáciu sa použijú odpadně vápenné kaly z výroby 2-merkaptobenztiazolu (kaptaxu), obsahujúce ako nečistoty vápenatá sol’ kaptaxu a živice vznikajúce pri výrobě kaptaxu. Po neutralizácii je hodnota pH 4 až 7, s výhodou 5 až 6,5. Po neutralizácii sa nerozpustné látky oddelia s výhodou sedimentáciou.
