【摘要】 本文研究了用紫外分光光度法测定面粉及面制品中过氧化苯甲酰的方法。探讨了样品处理,还原、蒸馏、吸收光谱等条件。本法回收率:92—110%,CV6.3%.检出(?):0.02g/kg,检测范围:0—1.3g/kg。满足了正常监督监测工作的需要。更多还原

【Abstract】 The method of determing benzyl peroxide in flour and flour food by UVS was studied. The conditions for sample disposition,reduction distillation and absorption spectrum were al- so studied.The recovery rate was 92% to 110%,CV,6.3%,the detection limit,0.02g/kg and the range of detection and 0—1.3g/kg.The method meets the needs of normal monitor and detection.更多还原
