A method of estimating urinary oxalate is described. Impurities which might otherwise interfere with the estimation are removed by means of an ion-exchange resin. The oxalate is then reduced to glycolic acid, which forms a coloured compound with chromotropic acid. It can then be estimated colorimetrically. No special equipment is required, oxalate recovery is good, and the method is reproducible and precise.
本文描述了一种估算尿草酸的方法。可能干扰估算的杂质通过离子交换树脂去除。然后将草酸盐还原为乙醇酸,乙醇酸与变色酸形成有色化合物。然后可以通过比色法进行估算。该方法无需特殊设备,草酸盐回收率良好,且具有可重复性和精确性。
