Shenyang Research Institute of Chemical Industry, Shenyang 110021, China Abstract: Spectrophotometric analysis showed that the peak absorbance for food dye of Allura Red and biological dye of Ponceau-G occurred at 501 and 510 nm. In sunlight after 2, 4, 6, 8, 10 hours, the decomposition rates of Allura Red and Ponceau G were between 2.4 to 5.8% and 3.4 to 10.8%, so they are stable in sunlight. The recovery rates on cottons and glasses were very high, so they are easily recoveried from targets. Further studies showed that the recovery rates of two dyes on the leaves of wheat, cabbage, cucumber and tomato were different, so it need previously determine the recovery rate of tracer on the target crop to adjust the result. Field experiment showed it was easy to measure the pesticide spray distribution of high volume spay and low volume spray to use Allura Red and Ponceau-G as tracers.
沈阳化工研究院,沈阳 110021 摘要:光谱分析表明,食品染色剂诱惑红和生物染色剂丽春红-G的最大吸收波长分别为501 nm和510 nm ;在连续2、4、6、8、10 h阳光照射下,分解率分别在2.4%~5.8%和3.4%~10.8%之间,见光稳定性良好;两种染色剂在棉花叶片和玻璃片上的洗脱回收率都很高,说明易于从靶标上洗脱下来;进一步测定表明,两种染色剂在小麦、甘蓝、黄瓜、番茄叶片上的洗脱回收率各不相同,所以对准备进行测试的作物应先做一次洗脱回收率试验,用以校正测试结果;田间应用表明,用两种染色剂做示踪剂,可以方便地测定常量喷雾和低容量喷雾过程中农药在麦田的沉积分布情况。
