A simplified wet-ashing technique is described for the determination of chelated iron in the urine, with special reference to DTPA-bound iron. The procedure dispenses with the need for quantitative transfer, and gives corresponding economy in time, labour, and glassware without loss of precision. The standard error of the mean estimate of a triplicate determination, using four reference standards, is +/- 4 mug/100 ml; precision may be further increased by the use of a calibration curve based on many standards.
本文描述了一种简化的湿灰化技术,用于测定尿液中的螯合铁,特别针对二乙三胺五乙酸结合铁。该方法无需进行定量转移,在不损失精度的情况下,节省了时间、人力和玻璃器皿。使用四个参考标准品进行三次重复测定的平均估计值的标准误差为±4微克/100毫升;通过使用基于多个标准品的校准曲线,可进一步提高精度。
