摘要
介绍了用钼蓝光度法准确测定铝箔制品中微量砷(质量分数不大于0.01%)的含量的方法,并对该方法的准确度、误差和影响因素进行了说明,此方法尤其适用于对药品、食品包装用铝箔中有害健康的元素砷的监控。
The process is introduced that determines accurately the content of fe w arsenic(not more than0.01%)in the aluminium foil products.Moreover,it explains at large about the accuracy、error、and influence matters of the meth od.The method is especially fit for the supervision and control of the arsenic that does harm to health in the drag&food-wrapping foil products.
