Heavy metal adsorption onto agro-based waste materials: a review.
Adsorption has been proved to be an excellent way to treat industrial waste effluents, offering significant advantages like the low-cost, availability, profitability, easy of operation and efficiency. Biosorption of heavy metals from aqueous solutions is a relatively new process that has proven very promising in the removal of contaminants from aqueous effluents. Biosorption is becoming a poten...
متن کاملHeavy Metal Waste Conversion by Thermally-Driven Chemical Bonding
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 d...
متن کاملSorption and Desorption of Chromium (III) from Aqueous Solution by Agro-Waste Materials
Agro-waste materials such as sorghum straw (SS), oats straw (OS) and agave baggasse (AB) contain several functional groups (carboxyl, carbonyl, acetamido, amino, hydroxyl, etc.) which are able to bind heavy metal ions present in aqueous solution. The major advantages of these materials are: low-cost, high efficiency and regeneration. The agro-waste materials studied in this research (water wash...
متن کاملAdsorption of Heavy Metal onto the Materials Prepared by Biomass
The amount of heavy metal ions released into the environment has been increased due to industrial activities and technological development. Furthermore, indiscriminate disposal has caused worldwide concern for many years because of the toxicity, accumulation in the food chain, persistence in nature, and concentration by organisms [1–3]. Heavy metals are not biodegradable and tend to accumulate ...
متن کاملAdsorption of Heavy Metal (Cu, Ni and Zn) from Synthetic Waste Water by Tea Waste Adsorbent
Industrial waste constitutes the major source of various kinds of metal pollution in natural water. There are at least 20 metals which cannot be degraded or destroyed. The important toxic metals are Cu, Ni and Zn. There are numerous methods currently employed to remove and recover the metals from our environment and many physicochemical methods have been proposed for their removal from wastewat...
