| description | The potential of aloe vera (AV) rhind powder in removing methylene blue (MB) from
aqueous solution was investigated. The AV was characterized by using Fourier
Transform Infrared (FTIR) absorption spectroscopy and Thermogravimetric analyzer
(TGA). The zero point charge was 6.25. The effect of pH, sorbent dosage, initial
concentration and contact time were investigated. The maximum uptake ofMB was at
pH 8 with 85 % removal. The adsorption equilibrium was established after 10
minutes. The adsoprtion of MB by AV increased with its initial concentration.
Pseudo-first and Pseudo-second order kinetic models were applied. The result showed
that pseudo-second order showed best fitted with high correlation (R2 > 0.995). It was
found that the adsorption fitted well with Freundlich isotherm equation. The study
suggested that AV could be an efficient sorbent for MB removal. |
