Retrieval of Precious Metal from Waste Effluent at Precious Plate Inc. in Niagara Falls , NY
Precious Plate, Inc. is a local electroplating company that uses a variety of metals during its processes. Post-deposition, the aqueous phase used is designated for disposal, which poses problems regarding the metal content of the waste stream. First, EPA regulations mandate that metals be kept below specific levels. Even at levels capable of meeting EPA limits, the loss of metals within their ...
متن کاملShort-term and long-term relationships between gold prices and precious metal (palladium, silver and platinum) and energy (crude oil and gasoline) prices
Throughout history, investors have attempted to determine the future states and prices of instruments that they consider to invest in. Thus, various econometric models have been developed in order to determine the variables influencing the prices of investment instruments, as well as the relationships between such variables. The main aim of the present study was to examine the variables that ma...
متن کاملCurrent advances in precious metal core–shell catalyst design
Precious metal nanoparticles are commonly used as the main active components of various catalysts. Given their high cost, limited quantity, and easy loss of catalytic activity under severe conditions, precious metals should be used in catalysts at low volumes and be protected from damaging environments. Accordingly, reducing the amount of precious metals without compromising their catalytic per...
متن کاملTitanium dioxide-supported non-precious metal oxygen reduction electrocatalysts
1. Materials synthesis and characterization Catalyst synthesis: Commercially available TiO 2 , with the particle size ranging from 50 to 150 nm and in the B.E.T. surface area from 50 to 100 m 2 /g, was first treated in 0.5 M HCl solution for 24 hours to remove impurities. In a typical approach to the synthesis of the PANI-Fe-TiO 2 catalyst, 2.0 mL aniline was first dispersed in 0.5 M HCl soluti...
متن کاملTitanium dioxide-supported non-precious metal oxygen reduction electrocatalyst.
A new non-precious metal oxygen reduction catalyst was developed via heat treatment of in situ polymerized polyaniline onto TiO(2) particles in the presence of Fe species. The TiO(2) provides for improved performance relative to a carbon black-based catalyst and, at a high catalyst loading, allows for reducing the performance gap between non-precious-metal catalyst and Pt/C to ca. 20 mV in RDE ...
