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...
