Preliminary Assessment of Chromium Emissions from Chromium Electroplating Faci Lities
The United States Environmental Protection Agency (EPA) intends to add either chromium or hexavalent chromium to the list of hazardous air pollutants under Section 112 of the Clean Air Act. A preliminary assessment performed by EPA has identified several categories of stationary sources as emitters of significant quantities of chromium to the atmosphere and for which the proposal o f national e...
متن کاملPreparation of the TiB2 coatings by electroplating in molten salts
The improvement of titanium diboride (TiB2) coatings over the molybdenum substrate was investigated by comparing the electrochemical techniques of continuous current plating (CCP) and periodically interrupted current (PIC). The solvent used was a eutectic Flinak mixture (LiF–NaF– KF, 46.5:11.5:42molar ratio) with solutes K2TiF6 andKBF4 with the electrochemically-active components in themolar ra...
متن کاملبررسی کاریوتیپی چهار گونه آویشن (Thymus spp) T. lancifolius) ،T. daenensis ، T. fedtschenkoi و pubescens T.)
آویشن (Thymus) از تیره Lamiaceae گیاهی است چند ساله که به‌دلیل خاصیت دارویی از اهمیت بالایی برخوردار است. بذرهای پنج جمعیت متعلق به چهار گونه T. Lancifolius،T. daenensis subsp. daenensis (دو نمونه)، T. fedtschenkoiو pubescens .Tکشت گردید و پس از جوانه‌زنی بذرها از مریستم انتهایی ریشه برای مطالعات کاریوتیپی استفاده شد. نتایج نشان داد که تعداد کروموزوم پایه در تمام جمعیت‌های مورد بررسی 15= x اس...
متن کاملA New Method for Electroplating of Crack-Free Chromium Coatings
In this study, different amounts of MoS2 particles and an anionic surfactant were added to the conventional chromium electroplating bath in order to electrodeposite crack-free chromium coatings and the structure, morphology, tribology and corrosion behavior of the deposited coatings were investigated using X-ray diffraction spectroscopy, scanning electron microscopy, pin on disk ...
متن کاملExtraction and recovery of chromium from electroplating sludge.
This work reports a study of the extraction and recovery of chromium from the wastes (class I dangerous) generated by a galvanic manufacturer. Commercial HCl at room temperature was employed, and the conditions of the extraction process were optimized according to a sequential experimental design, which also included the acid concentration and contact time as variables. The best extraction cond...
