Spectrophotometric Determination for Mercury(II),Lead(II) and Zinc(II) with 2-[(6- Methyl-2-Benzothiazolylazo)]-4-Chloro phenol as Organic Reagent
Abstract
A sensitive and selective spectrophotometric method is proposed for the rapid determination of Mercury(II),Lead(II) and Zinc(II) using (6-MeBTAClP), as spectrophotometeric reagent. The (6 –MeBTAClP) reagent gives intense green colour when reacts with these in acetate buffer solution. The maximum absorbance observed at 637 nm,651 nm and 610 nm for Hg(II),Pb(II) and Zn(II) respectively. The molar absorptivity for Mercury(II),Lead(II) and Zinc(II) complexes is (9521.2, 12714.2 and 12748.4) L.mol-1.cm-1 respectively. The Mole ratio 1:2 [M:L] for the complexes of Hg(II),Pb(II) and Zn(II). The linear range of(1-35),(1-18) and(1-16) respectively along with limit of detection 0.406, 0.05 and 0.188 μg mL-1. Relative standard deviation for seven replication measurements (2.71% Hg, 0.171% Pb and 0.209% Zn),and the recovery range of (97.43) , 97.65 and ( 97.95) were obtained for Hg(II), Pb(II) and Zn(II) ions ,and Erel=2.57 , 2.047 , 2.35 for Hg(II),Zn(II) and Pb(II) respectively. . The most important interference were due to Ni2+, Zn2+, Cu2+, WO4 2-, Pb2+,MoO4 2- , Hg2+, and CrO4 2- and suitable masking agents were used.
