摘要
大米是人们生活中不可缺少的主食粮食。所以，大米的农药残留量是否超出食用的安全标准，已成为各国关注的热点。但目前测定大米中农药残留量的方法操作条件要求严格，前处理繁琐，干扰严重，设备亦昂贵，影响测定工作开展。我们经过多次试验，优选出一种最优色诣条件，方法简单、快速、灵敏，结果准确，具有很高的实用价值。
Rice is a main food in people's life. So, whether the remaining pestcide exceeds over the safe standards has become an international ceoncern. The present determining methods of remaining pestcide in rice have disadvantages of strict operation, overlaborate pretreatment, serious disturbance and high equip- ment in vestment, whtich impede the monitoring. After experiments, an optimum monitoring method has been selected out. The simple operation, high sensitiyity and accurate results make it practicable.
