Heavy Metal Waste Conversion by Thermally-Driven Chemical Bonding
نویسنده
چکیده
Ceramic Bonding, Inc. (CBI) was founded in 1987 to develop technology for reliable, inexpensive, on-site conversion of heavy metal hazardous wastes to safe, useful materials, such as fine aggregate for construction applications. CBI’s principal mission is to provide equipment that can be used by industry to eliminate the need for costly and environmentally unwise disposal of toxics at Class I dumpsites.

Leaching of heavy metal from native plants by chemical leachants
Plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. This study provides an evaluation of extractants for the removal of lead from Abutilon Theophrastus biomass. The research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...
متن کاملMetal-centred azaphosphatriptycene gear with a photo- and thermally driven mechanical switching function based on coordination isomerism
Metal ions can serve as a centre of molecular motions due to their coordination geometry, reversible bonding nature and external stimuli responsiveness. Such essential features of metal ions have been utilized for metal-mediated molecular machines with the ability to motion switch via metallation/demetallation or coordination number variation at the metal centre; however, motion switching based...
متن کاملThermal Stability and Rehybridization of Carbon Bonding in Tetrahedral Amorphous Carbon
We preform a quantitative investigation of the energetics of thermally induced sp3 → sp2 conversion of carboncarbon bonds in tetrahedral amorphous carbon (ta-C) films by using near edge x-ray absorption fine structure (NEXAFS) and Raman spectroscopy. We investigate the evolution of the bonding configuration in ta-C thin films subjected to high temperature annealing in flowing Argon gas using a ...
متن کاملAgricultural waste material as potential adsorbent for sequestering heavy metal ions from aqueous solutions - a review.
Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...
متن کاملPhysical and chemical characterization of waste wood derived biochars.
Biochar, a solid byproduct generated during waste biomass pyrolysis or gasification in the absence (or near-absence) of oxygen, has recently garnered interest for both agricultural and environmental management purposes owing to its unique physicochemical properties. Favorable properties of biochar include its high surface area and porosity, and ability to adsorb a variety of compounds, includin...
