Ngwaahịa a bụ isi ihe eji eme electroplating na-enweghị cyanide. Mgbe e mere ya ka ọ bụrụ ihe ngwọta electroplating ọla kọpa na-enweghị cyanide, ọ nwere ike itinye akwa ọla kọpa ozugbo na ihe sodium-iron na njikọta dị mma. Mkpuchi ahụ nwere elu dị nro ma na-egbukepụ agba dị mma. Usoro izugbe nke ihe ngwọta ọdịnaya 60% bụ 100 ruo 120 ml kwa lita, usoro nke copper sulfate bụkwa gram 15 ruo 20 kwa lita. Na mgbakwunye, itinye akụkụ ndị a pịrị apị na ngwọta 1% ruo 2% nke ngwaahịa a iji mee ka elu ha rụọ ọrụ tupu electroplating nwere ike ime ka mmetụta electroplating dịkwuo mma.
Hydroxyethylidene Diphosphonic Acid (HEDP) bụ ụdị ihe mgbakwunye ọhụrụ nke na-enweghị chlorine. Ọ na-eje ozi dị ka ihe na-eme ka mmiri dị mma na sistemụ mmiri oyi na-agagharị ma na-arụ ọrụ na mgbochi nchara na mgbochi nha. Ọ bụ otu n'ime ihe ndị na-agwọ mmiri polyphosphonic acid organic. E nwere ngwaahịa ndị ọzọ a na-emepụta n'ime obodo, dị ka Amino Trimethylene Phosphonic Acid (ATMP) nwere usoro \([CH_2PO(OH)_2]_3N\), Ethylene Diamine Tetra Methylene Phosphonic Acid (EDTMP), na ndị ọzọ.
Acid polyphosphonic organic bụ otu n'ime ihe ndị e ji agwọ mmiri emepụtara na ngwụcha afọ 1960 ma mata ya n'ihe dị ka afọ 1970. Mpụta nke ihe ndị a dị elu nke ukwuu na teknụzụ ọgwụgwọ mmiri.
