groups. In summary, and under our conditions, ...
为解决竹红菌甲素(hypocrellin A,HA)易溶于有机溶剂却极难溶于水的问题,采用物理包埋法,以Triton X-100为载体,制备了对水稀释后稳定性良好的500 mg/L的竹红菌甲素Triton X-100微乳剂,并 测定了其光热稳定性及对植物病原菌的抑制活性。结果表明:在0~54℃、照度低于3 600 lx时, 该微乳剂的光热稳定性良好;在照度为7 200 lx时,50 mg/L的HA...
Triton X-114存在下镉试剂分光光度法测定环境水样中的镉
环境水样 镉 镉试剂 Triton X-114 表面活性剂 分光光度法
2014/5/30
及时监测环境水中的镉含量是预防和治理镉污染的前提,采用分光光度法测定镉具有简便、迅速、易普及等特点,然而较低的灵敏度限制了该方法的应用。本文通过选用表面活性剂Triton X-114为增敏剂,有效地提高了镉试剂分光光度法测定镉离子的灵敏度。研究结果表明,在KOH溶液中,Triton X-114存在下,镉试剂与镉离子生成橙红色络合物,显色物质最大吸收峰为470 nm,镉离子含量在0~10 μg/25...
