Recovery of Cu(II) by chemical reduction using sodium dithionite.
Wastewaters containing Cu(II) along with ligands are ubiquitous in various industrial sectors. Efficacy of treatment processes for copper removal, especially precipitation, is greatly debilitated by ligands. Chemical reduction being commonly employed for production of metal nanoparticles has also been used for removing copper. Addition of ammonia was reported to be essential for improving coppe...
متن کاملThe reduction of diphosphopyridine nucleotide by sodium dithionite.
It is well known that diphosphopyridine nucleotide (DPN) can be reduced by sodium dithionite to give a product, DPNH, identical with that obtained by enzymic reduction. DPN can also be reduced by ionizing radiations under special conditions (Swallow, 1953), but theproductwas found to possess no coenzyme activity when tested with lactic dehydrogenase (Stein & Swallow, 1954). Barron, Johnson & Co...

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولReduction of metmyoglobin derivatives by dithionite ion.
The rate constants for reduction by dithionite of a number of metmyoglobin species Mb+X(X=H2O, imidazole, OH-, F-, N3-, CNO-, SCN-, HCO2-, NO2-, and CN-) were measured at 25 degrees by stopped flow spectrophotometry. The dependence of the rate was [S2O42-]1/2, and the SO2- radical was considered to be the active reductant. Except for X=imidazole and CN-, reduction occurred through dissociation ...
