Removal of reactive red 198 dye from aqueous solution by activated oil palm kernel shell / Nursyaza Husna Shaharuddin

The adsorption behavior of Reactive Red 198 (RR198) from the aqueous solution onto activated palm kernel shell (APKS) was investigated under several different operating parameters (contact time, adsorbent dosage, pH, particle size, initial dye concentration and temperature). APKS was shown to be...

APKS was shown to be effective in removing reactive dye. At temperature 25, 30 and 35°C percent of removal of RR198 was increased respectively. Meanwhile, at pH 4, 7, 9 and 11, percent of removal of RR198 was decreased respectively. These indicated that the process is endothermic reaction and the anionic species of RR198. On the other hand, the adsorbent was characterized under several methods which are ash content, apparent density, SEM, and FTIR.

In this study, exponent,n was 1.949 (1< n< 10) shows that Freundlich isotherm best-fit the equilibrium data for adsorption of RR 198 dye on activated PKS.
