Determination of Copper and Zinc in Sugar-

Since the introduction by Walsh12 in 1955 of atomic absorption spectrophtometry as an analytical method, it has found application in many fields as a means of rapid analysis of certain metallic elements at very low concentrations. The analysis of agricultural materials, i.e., leaves, soil extracts and fertilizers is one sphere in which atomic absorption has been applied by several workers1, 2, ...

determination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid

چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...

Determination of copper and zinc in blood plasma by ion chromatography using a cobalt internal standard.

Ion chromatography was used to detect levels of copper and zinc in blood plasma from renal dialysis patients on continuous ambulatory peritoneal dialysis (CAPD) and haemodialysis (HD). The developed method used cobalt as an internal standard and when combined with the standard additions method improved the overall precision of the results by between -0.3 and 6.0% and -0.8 and 5.7% for copper an...

Direct determination of plasma copper and zinc in infants by atomic absorption with discrete nebulization.

A new micromethod for the determination of copper and zinc is presented. Sample volumes can be as little as 10 (Cu) and 20 (Zn) microliter of plasma or serum, by using discrete (small sample volume) nebulization in place of conventional nebulization in place of conventional nebulization in atomic absorption spectrometry. The present method has slightly poorer precision than the conventional neb...
