Adsorption of manganese and zinc in synthetic wastewater by tea waste (TW) as a low cost adsorbent
In this study, tea waste (TW) is investigated as a low cost adsorbent for the treatment of Mn(II) and Zn(II) in synthetic wastewater. Experimental design, the variables are the adsorbent dosage (0.5g, 1.0g, 1.5g, 2.0g, 2.5g and 3.0g) and contact time (20, 40, 60, 80, 100 and 120 minutes). The percen...

In this study, tea waste (TW) is investigated as a low cost adsorbent for the treatment of Mn(II) and Zn(II) in synthetic wastewater. Experimental design, the variables are the adsorbent dosage (0.5g, 1.0g, 1.5g, 2.0g, 2.5g and 3.0g) and contact time (20, 40, 60, 80, 100 and 120 minutes). The percentage of heavy metal ions removal in the solution are measured using DR2800 Spectrophotometer. Adsorption Isotherm and Adsorption Kinetic modelling are applied to further prove the correlation of the experimental data obtained for the removal of Mn(II) and Zn(II). The equilibrium data satisfactorily fitted into Langmuir Isotherm model for both Mn(II) and Zn(II) with R2 value of 0.9906 and 0.9854, respectively.
