The main disadvantage of activated carbon is its high cost in manufacturing and treatment. Therefore there is a need to continue the search and developing alternative adsorbents with high adsorptive capacity and low cost for HA removal. In this study, we investigated the effect of temperature on adsorption of Methyl Orange (MO) onto polymethyl methacrylate (PMMA) nanofiber to be used as an adsorbent. Adsorption experiments were carried out by mixing respectively of 0.05 g PMMA nanofiber with 50 mL of MO 100 mg/L at 25 oC, 45 oC and 65 oC in thermostatic shaker bath for 2, 5, 10, 15, 20, 25, 30, 45, 60, 90, 120 and 150 minutes. At the end of the predetermined time interval, a 0.45 ┬Ám Uniflo filter was used to separate the suspension. The clear solution was analysed for the remaining MO concentration by an ultraviolet-visible spectrophotometer model UV-Vis 1601 (Agilent 8453, USA) at the λ 463.5 nm. The percent of MO adsorption was calculated using the following equation: Adsorption (%) = [(Ci-Ce)/Ci] x 100%, where Ci and Ce are initial and final concentration of MO in solution, respectively. The adsorption capacity of an adsorbent at equilibrium with solution volume V was calculated using the following equation...
