A novel dual-colour reagent and dual wavelength spectrophotometric method for the determination of mic-roamounts of mercury is established by adding another colour reagent -biscyclohexanone- oxaldihydrazine (BCO) to the reacting system of mercury and copper di-ethyl-dithiocarbamate complex (Cu(DDTC)_2). The decrease of the absorbance (A_1) of Cu(DDTC)_2 and the increase of the absorbance ( A_2) of Cu (BCO)_2 are determined at 450nm and 600nm respectively,and mercury is determined from the summation of A_1and...

A novel dual-colour reagent and dual wavelength spectrophotometric method for the determination of mic-roamounts of mercury is established by adding another colour reagent -biscyclohexanone- oxaldihydrazine (BCO) to the reacting system of mercury and copper di-ethyl-dithiocarbamate complex (Cu(DDTC)_2). The decrease of the absorbance (A_1) of Cu(DDTC)_2 and the increase of the absorbance ( A_2) of Cu (BCO)_2 are determined at 450nm and 600nm respectively,and mercury is determined from the summation of A_1and A_2. Beer's law is obeyed for mercury ranging 0~200μg/25mL. The molar absorptivity is 3. 7×10~4L·mol~(-1)·cm~(-1). The detection limit is 0.14ppm. The standard reference material was determined with relative errors less than 2% and the coefficient of variation less than 5%.

对Cu(DDTC)_2+Hg~(2+)=Hg(DDTC)_2+Cu~(2+)褪色反应,加入另一种显色剂进行显色反应Cu~(2+)+2BCO=Cu(BCO)_2,在450nm处测量Cu(DDTC)_2吸光度的减少,600nm处测量Cu(BCO)_2吸光度的增加,以两处吸光度差值的和作Hg~(2+)的定量测定,从而建立了测定微量汞的双显色剂双波长分光光度法。该方法的ε=3.7×10~4 L·mol~(-1)·cm~(-1)。检出限为0.14ppm,标准物质检验的相对误差和变异系数分别小于2%和5%。

flow injection-dual-wavelength spectrophotometricmethod using chromazurol S and nitroso-R-salt as thechromogenic agents was developed to determine alumi-nium and iron simultaneously.The linear ranges for alu-minium and iron are 0 ~ 50μg/25mL and 0~200μg/25mL respectively, It is possible to get a routine samplingrate of 360 samples per hour.This method has been usedto determine aluminium and iron in rocks with satisfac-tory results.
