Heavy Metal Removal Using Dithiocarbamates
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...

متن کاملRemoval of Toxic Metals from Metal Finishing
An Adsorbent based treatment system is presented for toxic metal removal from rinsewater streams. The adsorbent is a Mg-A1 oxide anion exchange material with high capacity (approaching 5.5 meq/g) and strong selectivity for difficult to treat species such as Electroless plating metal chelates, Fixed Cyanides and chrome conversion solutions. Data is presented describing treatment of various metal...
متن کاملObservations on removal of metal implants.
A total of 86 adult patients who underwent routine surgery to remove metal internal fixation devices were studied prospectively. At the time of surgery, 46 patients were symptomatic, but only 27 requested surgery; 59 were admitted for routine surgery on medical advice. There was no correlation between symptoms, the length of time the implant had been in situ or the location of the implant. Good...
متن کاملOptimizing Metal-Removal Processes for Produced Water With Electrocoagulation
gas basin. For example, recycled produced water is less than 10% of the total water used to drill and fracture in the Barnett, Fayetteville, and Haynesville shale plays. However, the fraction of water recycled is significantly higher in the Marcellus play—greater than 90% of the total water used (Mantell 2011). Although treatment methods have been developed to recycle produced water for subsequ...
