Çeliğin galvanizlenmesi, çelik yüzeyini korozyondan korumak için uzun yıllardır uygulanan önemli bir endüstriyel işlemdir. Çinko-nikel alaşım kaplama, diğer çinko kaplama teknolojilerine kıyasla daha iyi mekanik özelliklere, yüksek korozyon direncine sahip olduğundan birçok endüstride yaygın olarak tercih edilmektedir. Ağır metal endüstrisi proseslerinde kullanılan çeşitli kimyasallar ve hammad...

As discharge restrictions become stricter and sludge dlisposal costs rise, traditional technologies for the removal of metals from plating shop wastewater such as lime and ferric chloride become increasingly less attractive. One technology that is of use of dithiocarbamates to complex a highly insoluble, dense sludge, effluent water and greatly reduced sludge volumes. Despite the benefits avail...

Very often electroless electrolytes contribute to wastewater treatment problems. These electrolytes are used in electroless plating processes, which contain a variety of chemicals to meet special surface treatment requirements. Metal salts produce the base material for metal deposition and hypophosphite is delivering the electrons for the metal reduction process – it is basically the internal e...

Activated carbon prepared form coconut residues (CORC), and agricultural waste byproduct obtained after oil extraction was used for the adsorption of Ni(II) form aqueous solution. The process of uptake obeys both Freundlich and Langmuir adsorption isotherms. Kinetic studies indicate that it obeys Lagergram kinetic model. Quantitative removal of Ni(II) from 100mL aqueous solution containing 10mg...

ajor emphasis is placed today on treating plating solutions and rinsewater to reduce the concentration of toxic metals to below established limits prior to discharge or water reuse. Available technology is adequate for partial treatment of most wastewater; however, new technology is needed to scavenge heavy metals from complexed or chelated compounds in rinsewater. Several report^^-'^ from this...
