The materials mentioned above are reextracted from an ether solution by 2 N sodium hydroxide. The UV extinction of the aqueous layer at 232 nm and 30 degrees C is followed by means of a slave recorder. The original extinction is found by back-extrapolating to the time of re-extraction. It has to be corrected for the "biological matrix" by subtracting the extinction value after complete hydrolysis. Most interfering substances in the ether solution (carboxylic acids, barbiturates) may be removed previously by washing with aqueous buffers (pH 7.0 and 10.5).
上述材料用2N氢氧化钠从乙醚溶液中重新萃取。水层在232nm波长和30℃下的紫外吸光度通过从属记录仪进行跟踪。通过反向外推至重新萃取的时间来确定原始吸光度。必须通过减去完全水解后的吸光度值来校正“生物基质”的影响。乙醚溶液中的大多数干扰物质（羧酸、巴比妥酸盐）可事先用水性缓冲液（pH 7.0和10.5）洗涤去除。
