Response s urface methodology was used to determine the optimal measure condition s: bath temperature 85 ℃, ultrasonic power 200 W and ultrasound time 30 min. The soy isoflavone concentration in the wastewater was 0.367 g /L and the relative error was only 3.4% compared with the result of 0. 380 g/L measured by high performance liquid chromatography. The method has the advantages of simple instrument and fast measurement and thus , it can be used in industrial production to measure the soy isoflavon e concentration of the wastewaters. %K 大豆异黄酮 %K 大豆乳清废水 %K 分光光度法 %K 超声水浴 %K 响应面< %K /br> %K soy isoflavone %K soy whey wastewater %K spectrophotometry %K ultrasonic bath %K response surface %U http://zrxuebao.hebut.edu.cn//oa/darticle.aspx?type=view&id=201304011
