将几种常见无机化合物的水溶液通过一定的组合,应用紫外可见吸收光谱法筛选出四种具有一定滤光宽度的溶液滤光片:①40% 硝酸铜水溶液-40% 硝酸钴水溶液(380±30 nm ,41% );②50% 三氯化钴-5% 硫酸铬水溶液(325±40 nm ,42% );③40% 氯化镍-40% 硝酸铜水溶液(500±35 nm ,46% );④40% 氯化镍-5% 硝酸铬水溶液(330±15 nm ,18% ;500±40 nm ,40% ).将氢灯光束通过滤光片①滤光诱导6-[4-(4-十二烷基苯基偶氮基)-1-萘氧基]己酸(Ⅰ)在氯仿溶液中从反式→顺式的异构化,并测定了其在黑暗中从顺式→反式转化的动力学性质
Several kinds of common inorganic compounds aqueous solution through a certain combination of UV-visible absorption spectroscopy filter out a filter with a certain width of the filter: ① 40% aqueous solution of copper nitrate-40% aqueous solution of cobalt nitrate (380 ± 30 nm , 41%); 50% cobalt trichloride-5% chromium sulfate aqueous solution (325 ± 40 nm, 42%); 40% nickel chloride-40% copper nitrate aqueous solution (500 ± 35 nm, 46% Nickel chloride-5% aqueous solution of chromium nitrate (330 ± 15 nm, 18%; 500 ± 40 nm, 40%). The hydrogen lamp was filtered through filter ① to induce 6- [4- Phenylazo) -1-naphthalenyloxy] hexanoic acid (I) was isomerized from trans to cis in a chloroform solution and the kinetics of its conversion from cis to trans in the dark were determined Learning nature
