Abstract

Industry produces phenol liquid waste that pollute the environmental. Phenol is a dangerous organic compound that has hight toxicity so that the presence of phenol in the environment will disrupt the surrounding ecosystem and have an impact on human health. To overcome the problem of environmental pollution, an adsorption method is used by utilizing longan skin as an adsorbent. Lengkeng shell is used as an adsorben able to bind phenol in the environment because it has several active groups such as amines, hydroxyl, carbonyl, and carboxyl which can form hydrogen banding with phenol solution. The purpose of this study was to determine the optimum conditions with variation in adsorbent particel sizes of 106, 150, 250, and 425 mm and stirring speeds of 50, 100, 150, 200, and 250 rpm. Phenol was analyzed using UV-Vis spectrophotometer (Specord 210). Adsorption phenol with lengkeng shell biosorbent obtained optimum conditions at an adsorbent particle size of 106 with adsorption capacity of 4.583 mg/g and stirring speed of 200 rpm with adsorption capacity of 4.200 mg/g.
