利用KBrO3-Ce(SO4)2-CH2(COOH)2-H2SO4 敞开体系研究测定黄河水中苯酚污染物的新方法,在连续搅拌反应器 (CSTR)中 ,当[KBrO3]=0.0625mol/L,[CH2(COOH)2]=0.187mol/L,[Ce(SO4)2]=0.002mol/L,[H2SO4]=0.8mol/L,蠕动泵单路流速为1.2mL/min时 ,苯酚的质量浓度在0.10～25mg/L范围内与振幅的改变、周期的改变呈线性关系 ,检出限为0.05mg/L ;苯酚的加标回收率为95 %～102 %。
A new method for the determination of phenol contaminants in the Yellow River water was developed by using KBrO3-Ce (SO4) 2-CH2 (COOH) 2-H2SO4 open system. When [KBrO3] = 0.0625mol / L, The results showed that the mass concentration of phenol in the single-pass peristaltic pump was 1.2mL / min when the concentration of H2O2 and CH2COOH2 were 0.187mol / L, [Ce (SO4) 2] = 0.002mol / L, [H2SO4] In the range of 0.10-25 mg / L, the linear relationship between the amplitude and the change of the cycle was obtained. The detection limit was 0.05 mg / L and the spiked recoveries of phenol ranged from 95% to 102%.
