合成了一种新的三氮烯类试剂1-( 4-硝基苯基)-3-( 2-苯并噻唑)-三氮烯,并研究在表面活性剂Tween-100存在下与钯的显色反应. 钯与试剂在pH11.0 0的Na2 B4 O7-NaOH缓冲介质中形成摩尔比为3 :1的橙色稳定配合物. 其表观摩尔吸光系数为1.94×105L· mol-1· cm-1,Pd(Ⅱ)的浓度在0.00~0.036μg/mL范围内符合比尔定律.
閤成瞭一種新的三氮烯類試劑1-( 4-硝基苯基)-3-( 2-苯併噻唑)-三氮烯,併研究在錶麵活性劑Tween-100存在下與鈀的顯色反應. 鈀與試劑在pH11.0 0的Na2 B4 O7-NaOH緩遲介質中形成摩爾比為3 :1的橙色穩定配閤物. 其錶觀摩爾吸光繫數為1.94×105L· mol-1· cm-1,Pd(Ⅱ)的濃度在0.00~0.036μg/mL範圍內符閤比爾定律.
