A method for the removal of metal cyanides or oxoanions from aqueous streams such as waste water streams with compounds containing 1,4-diazabicyclo[2.2.2]octane. Preferred compounds are polymers formed by free radical polymerization of N-4-vinyl benzyl-N1-1,4-diazabicyclo[2.2.2]octane dichloride (VBBD) such as copolymers poly (VBBD/acrylamide) and poly (VBBD/dimethyl amino ethyl acrylate benzyl chloride quaternary salt. Poly(1,4-dimethylbenzyl-1,4-diazabicyclo[2.2.2]octane dichloride) for the same purposes is also disclosed.
