应用
Potassium oxalate hydrate is used as a chelating agent, a purifying agent in the pharmaceutical industry and a precipitating agent in rare-earth metal processing. It finds application as a grinding agent, as a rust remover in metal treatment and as a bleaching agent in the textile and wood industry. It is also used in waste water treatment and as a scale remover in automobile radiators. Furthermore, it is used as a reagent in analytical chemistry for the determination of calcium and other heavy metals as well as reducing agents in photography. It is also involved in the preparation of SBA-15 (nanostructured SiO2) supported vanadium oxide catalyst.

备注
Hygroscopic. Incompatible with halogens, ammonia, cyanides and heavy metals.
