title: Atomic absorption and UV-VIS absorption spectrophotometric determination of oxalate in urine by ligand exchange extraction.
abstract: A new method for oxalate determination in urine is described. It neither requires precipitation nor previous extraction of oxalate and is free from the interferences often found with analyses of urine samples. The method is not time consuming and is suited to routine work.
