Abstract
Abstract
This research involve determination of Cu(II) by use a new reagent 2,2/-[(1,1/-Biphenyl)-4,4/-diyl bis-(azo)]-bis-[4,5-diphenyl imidazole] ( Bbai ), the wavelength of maximum absorption copper (Bbai) complexes at 588 nm
After optimum condition were constructed, Beer's law was obeyed in the range (0.4-2) ppm, the linearity ( R2 ) was (0.9998), correlation factor (r) was (0.998) and molar absorpitivty (ε) was 4.1395x 104 L.mol-1.cm-1.
The stoichometry of metal to reagent were (1:1), Precision and accuracy of the analytical procedure was R.S.D % (0.4) % and (Erel. Re) % were (-3.5, 96.5) %, detection limit was (0.03) ppm, the interferences of ions (CrO42-, Mn2+, Co2+, Ni2+, Zn2+, Cd2+ Ag+, Fe3+, Pb2+, Mg2+, Ca2+, Hg1+, Hg2+) were study and masked by using sutable masking agents.
