A catalytic reductive fading spectrophotometric method for determination of trace copper(Ⅱ) in Mongolian medicines

SHA Ren~ and WU Dubala(Chemistry & Environment Science College of Inner Mongolia Normal University,Inner Mongolia,Huhhot 010022)  
A new kinetic photometric method for the determination of trace amounts of copper is established,based on the discoloring reaction of ascorbic acid reducing chlorophosphonazo-mA,which is catalyzed by Cu(Ⅱ) in the presence of cetyltrimethylammonium bromide and α、 α-Dipyridyl.A fixed time method is used to monitor the catalytic reaction at 554 nm.The linear range is 0~0.11 μg/mL,the detection limit is 6.3×10~(-11) g/mL and relative stardard deviation is 3.6%.This method has been used for the determination of trace amounts of copper in many kinds of Mongolian medicines and the results obtained are satisfactory.
