Spent Tea Leaves as a Potential Low-cost Adsorbent for the Removal of Azo Dyes from Wastewater
Spent tea leaves (STL), a solid waste that is available in large amounts worldwide, was investigated as a potential low-cost adsorbent for the removal of two azo dyes, Reactive Green 19 (RG19) and Reactive Violet 5 (RV5), from contaminated waters. Preliminary experiments conducted on untreated STL showed that this material exhibited very low removal efficiencies (<10 %). By contrast, thermal ac...
متن کاملADSORPTION STUDY OF Cr(VI) FROM AQUEOUS SOLUTION USING ANIMAL BONE CHARCOAL AS LOW COST ADSORBENT
Animal bone charcoal (ABC) produced from animal bones was used as adsorbent to remove Cr(VI) from its aqueous solution . Labority experimental investigation was carried out to identify the effect of contact of time, pH, adsorbent dose and initial concentration on the adsorption of chromium from metal solution. Results showed that pH 2 was the most suitable, while the removal of Cr(VI) ions with...
متن کاملAdsorption of Copper from Aqueous Solution Using Low- Cost Adsorbent
In this study activated carbon prepared from Adathoda vasica stem was used as adsorbent to remove Cu from an industrial waste water. For this purpose, high grade CuSO4.5H2O was used as heavy metal sample. Laboratory experimental investigation was carried out to identify the effect of pH (1.50 – 5.5), agitation time (30-240 min) varying temperature (30-50 ̊C) and varying biomass quantities (2,4,6...
متن کاملAdsorption of Chromium (VI) by a Low-Cost Adsorbent Prepared from Tamarind Seeds
The presence of toxic heavy metals such as chromium (VI) contaminants in aqueous streams, arising from the discharge of untreated metal containing effluents into water bodies, is one of the most important environmental problems. Adsorption is one of the effective techniques for chromium (VI) removal from wastewater. In the present study, adsorbent is prepared from tamarind seeds and studies are...
متن کاملBiotransformation of chromium (Cr-VI to Cr III) from tannery effluent using bacteria and fungi
Chromium, a priority pollutant is well known for its mutagenicity, carcinogenicity and teratogenicity in humans, animals and plants. Extensive use of chromium in industries such as leather tanning, stainless-steel production, electroplating and wood preservatives have resulted in extensive chromium contaminated soil and ground water. Microorganisms are involved in the removal of toxic wastes, b...
