Approximately 10-15 % of usage synthetic textile dyes are released to waste streams meanwhile the effluent release from wastewater treatment plant contribute 20 %. Adsorption being a physical process, inexpensive and less time consuming, is widely accepted eliminate wastewater. An experiment was carried out observe adsorption Brilliant Green Procion Red dye. The identify most effective adsorbent remove colour Red. Both were mixed with agricultural wastes, spent tea leaves, jackfruit peels,...

High amounts of ammonium (NH4+) discharged in receiving water can lead to eutrophication. The adsorption NH4+ from synthetic solution onto granular activated carbon (GAC) was scrutinized with respect initial solute concentration (10 mg L−1), volume (0.2 L), adsorbent dosage (4 – 20 g), and contact time. Experimental data be well described by the pseudo-second-order kinetic model (R2 > 0.994) Freundlich isotherm = 0.936), suggesting that chemisorption multilayer occurred. Furthermore, this...

High amounts of phosphate (PO43–) discharged in receiving water can lead to eutrophication, which endangers life below and human health.
