Removal of heavy metals from waste water using different biosorbents
The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...
متن کاملColumn operation studies for the removal of dyes and phenols using a low cost adsorbent
Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...
متن کاملInvestigation of heavy metals in mint plants irrigated by wastewater: a systematic review and meta-analysis
Background and Objective: Nowadays, water shortage crisis leads to wastewater reuse in agriculture sector. The presence of pollutants such as heavy metal in wastewater results in the accumulation of them in vegetables, and it will finally be transferred to consumers and will have irreversible effects on their health. Therefore, the present study was performed to do a systematic review along wit...
متن کاملA review study of biosorption of heavy metals and comparison between different biosorbents
With rapid industrial development, problems related to pollution are becoming severe Water pollution is one of the most serious problems because inorganic and organic wastes are discharged to the aquatic environment either in water soluble or insoluble forms. Heavy metal ions have lethal effects on all forms of life and these enter the food chain through the disposal of wastes in water channels...
متن کاملLow-cost adsorbents for heavy metals uptake from contaminated water: a review.
In this article, the technical feasibility of various low-cost adsorbents for heavy metal removal from contaminated water has been reviewed. Instead of using commercial activated carbon, researchers have worked on inexpensive materials, such as chitosan, zeolites, and other adsorbents, which have high adsorption capacity and are locally available. The results of their removal performance are co...
