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 کاملRecovery of Metals from Electroplating Wastes
Disposal of metal finishing wastes is one of the most critical industrial waste problems in the United States today. Recent legislation greatly restricts the discharge of most heavy metals to watercourses and future discharge regulations may further restrict their release to the environment. Furthermore, interest in developing possible methods for reclaiming metals from plating waste streams is...
متن کاملSolvent Extraction Of Chromium (VI) From Aqueous
The extraction of chromium (VI) from hydrochloric, hydrobromic, and acetic acid solutions with Tri caprylamine oxide (TCAO) in benzene has been studied. The extractions from hydrochloric and hydrobromic, acid solutions are nearly quantitative and are partial from acetic acid solutions. The optimum conditions for extraction were established from the study of the effect of several variables like–...
متن کاملTreatment of Electroplating Wastes
~sing of the environment, the electroplating industry is likely to be one of the industries to be affected by the introduction of the water pollution control legislation in Hong Kong. The effect may be even more pronounced for the operators of small and medium-sized electroplating factories since they are unlikely to have any expertise in pollution control and will therefore require outside tec...
