Utilization of Solid Biomass Waste (Oil Palm Frond) as Low-Cost Adsorbent for Janus Green B Dye Removal

Dye waste in water pollution has become a major environmental issue that causes
insecurity, health disorder and interference with the nature’s law of ecological balance.
As we advance in the modern world, strict legal limits imposed on waste water
discharge has urged the needs for new technical applicability and cost-effective
method for water treatment. Recently, the study of using raw biomass for removing
dye has drawn attention of various researchers. It is highly recommended to develop a
low-cost adsorbent from agricultural waste or industrial by-product that will add value
to the waste. Thus, this project aimed to evaluate the potential of oil palm frond (OPF)
in removing Janus Green B (JGB) dye. The prepared biomass were subjected to dye
adsorption studies and the effect of pH, initial dye concentration and biomass loading
were studied. The adsorption capacity increased with an increased in initial dye
concentration.
