Determination of Oxalate in Urine Using Oxalate Oxidase: Comparison with Oxalate Decarboxylase [PDF]
Clinical Chemistry and Laboratory Medicine, 1979 The oxalate content of urine is determined by means of oxalate oxidase and simple pH measurement. The enzyme specifically decarboxylates oxalate, producing two moles CO2 per mole oxalate. The CO2 diffuses into an alkaline buffer solution (Hallson, P. C. & Rose, G. A. (1974), Clin. Chim. Acta 55, 29--39) in the closed reaction vessel, and reduces the pH

Decomposition of Bayer process organics: Phenolates, polyalcohols, and additional carboxylates [PDF]
, 2011 The degradation of nineteen low-molecular-weight phenolates, polyalcohols and selected aliphatic and aromatic carboxylates of relevance to the Bayer process has been studied in 6 mol kg-1 NaOH(aq) at 90 °C for up to 36 days, and (for some species) at 180
