Vehicle powder coating system
A method of removing cyanide ion from wastewater comprising providing wastewater containing cyanide ion and having a pH below 2; adding a quantity of an Fe2+ ion source to the wastewater, and causing the Fe2+ to react with the cyanide ion to form a reaction product Fe4[Fe(CN)6]3 and separating the reaction product from the wastewater.

An adhesive for electroless plating obtained by dispersing cured particles of heat-resistant resin soluble or decomposable in an acid or an oxidizing agent into an organic solvent to form a dispersion and mixing with an uncured resin and a heat-resistant thermoplastic resin, characterized by in that the dispersion of the cured particles of the heat-resistant resin in the production of heatresistant resin cured particles into the organic solvent without drying, and the uncured resin is a resin becoming hardly soluble in an acid or an oxidizing agent thorough curing treatment and capable of forming a heat-resistant cured resin.
