The condition of the aquatic environment is getting worse. This is due to the <br /> <br /> growing number of industries which resulted in the increase of waste generation. <br /> <br /> In addition, domestic waste is also a cause of water pollution. One of the <br /> <br /> compounds that cause the contamination is a phenol compound. Phenol is <br /> <br /> produced from industrial waste such as paper, textile, gas and manufacturing <br /> <br /> cokes, plastics and others. Phenol is toxic so its presence in water is very <br /> <br /> dangerous. Therefore, the removal of phenol is necessary and among various <br /> <br /> treatment method available for phenol removal, adsorption is enviromental <br /> <br /> friendly method and the best method for removal waste in water. Carbon is <br /> <br /> usually used as a phenol adsorber in the form of activated carbon, but it is <br /> <br /> relatively expensive. So it necessary to use material that cheap and <br /> <br /> environmentally friendly to adsorb phenol. The material that can be used is <br /> <br /> agricultural products waste, which contain cellulose, hemicellulose, lignin, <br /> <br /> proteins, simple sugars, water, hydrocarbons, and some functional groups to <br /> <br /> adsorb phenol compounds in solution. One such agricultural waste is a Chinese <br /> <br /> cabbage. This study aims to determine the absorption of chinese cabbage to <br /> <br /> removal phenol from aqueous solution. The adsorbent will make into powder and <br /> <br /> treatment using epichlorohydrin and HCl. Then, adsorbent characterized by SEM, <br /> <br /> FTIR, and BET. The removal phenol is investigated in terms of various <br /> <br /> parameters: pH range 5-9, contact time 20-80 min, adsorbent dosage 0,2-1,1 gram <br /> <br /> and adsorbat concentration 10-50 mg/L. Filtrat will be measured using a HPLC <br /> <br /> with the mobile phase was methanol : water (70:30 v/v), 0,8 mL/minute of flow <br /> <br /> rate at wavelength of 273 nm. The result of adsorption for adsorbent untreatment, <br /> <br /> adsorbent treatment with epychlorohydrin, and adsorbent treatment with HCl was <br /> <br /> 16,58%; 9,78%; and 9,96%. The optimum conditions were pH 8, contact time 40 <br /> <br /> minute, adsrobent dose 0,8 gram and initial concentration 10 mg.L-1.
