Use of Electroplating Industry Sludge as a Construction Material
Every industrial unit generates wastes along with the processed goods. These wastes actually represent loss of the valuable material and energy from the production processes and investment in the pollution control. Usual approach followed by the industries, to cope with the problem of wastes and pollution, is use of waste treatment systems as end-of-pipe remedies. The remedies adopted often res...
متن کاملNickel removal from electroplating industry wastewater: A bamboo activated carbon
Water is prime requirement for surviving of any living beings. The existence of surface water and groundwater sources are used for domestic, agriculture and industrial purposes in all over the world. Fresh water from both the water sources is highly contaminated in recent years because of rapid population growth, modern agriculture and industrial growth. Among them, contamination of water sour...

بررسی نقش گفتمان در شکل گیری یا کاهش انگیزش فراگیران زبان خارجی موضوع تحقیق نسبتاً جدیدی است. از این رو، تحقیقات کمی در این زمینه وجود دارد. به منظور پر کردن این خلاء ، مطالعه کنونی به بررسی فرآیند گفتمان مدار شکل گیری یا کاهش انگیزش دانشجویان ایرانی زبان انگلیسی پرداخت. نخست، این مطالعه به صورت آزمایشی با 7 نفر (? دانشجوی پسر و 5 دختر) از دانشجویان سال دوم دوره ی کارشناسی زبان و ادبیات انگلیسی ...
Extraction 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...
متن کاملFate of zinc in an electroplating sludge during electrokinetic treatments.
Chemical structure of zinc in the electrokinetic treatments of an electroplating sludge has been studied by in situ extended X-ray absorption fine structural (EXAFS) and X-ray absorption near edge structural (XANES) spectroscopies in the present work. The least-square fitted XANES spectra indicate that the main zinc compounds in the sludge were ZnCO(3) (75%), ZnOSiO(2) (17%) and Zn(OH)(2) (7%)....
