Eggshell as adsorbent for bromophenol blue dye removal

Water pollution is one of the main pollution in the worldwide due to increase of industry of textile, food and agriculture. The water pollution becomes negative impact to human and ecosystems. As the pollution rise and cost for treatment of water pollution is expensive the worldwide has find solution by using waste from agriculture to produce adsorbent. The adsorbent from agriculture waste was used widely for wastewater treatment because it contains highly removal capacity. Hence, the agriculture waste also low cost and can continuously been investigated. This research attempt to study the adsorption of Bromophenol Blue dyes removal by using eggshell as adsorbent. The objective of the research is to provide activated carbon from eggshell. Hence, the adsorption was determine by using ultra violet visible (uv-vis) of Bromophenol Blue is 465nm. The result shows that the adsorption process increased with the increased of time (10, 20, 30, 40 and 50 minute), the adsorption process decreased with the increased of concentration of dyes (20,40,60,80 and 100mg/L), the adsorption process of adsorbent dosage shows decreased (1,2,3,4 and 5 gram) and pH (2,4,6,7,8 and 10). This results shows that eggshell can be used as a suitable adsorbent for removal dyes.
