Spectrophotometric Determination of Uranium Using 2-(2-Thiazolylazo)-p-Cresol (TAC) in the Presence of Surfactants
No presente trabalho apresenta-se um método seletivo e sensível para rápida determinação de urânio usando o 2-(2-Tiazolilazo)-p-Cresol (TAC). O TAC reage com o urânio(VI) em pH 6,5 formando um complexo estável por pelo menos 3 h. Brometo de N-cetil-N,N,N-trimetil amônio (CTAB) e triton X-100 foram usados para aumento da sensibilidade e solubilidade do sistema respectivamente. O método permite a...
متن کاملdetermination 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 ...
15 صفحه اولInteraction of phenol derivatives with ion channels
Phenols began to play a prominent role very early in modern operative medicine in the 1860s when Lister introduced his ‘antisepsis’ approach. The treatment of open wounds by carbolic acid dramatically reduced morbidity and mortality of surgical patients for the first time [1]. This central place in operative medicine was lost when, in the early 20th Century, ‘asepsis’ replaced ‘antisepsis’. The...
