dc.description.abstract	The raw kaolin itself was a good adsorben . Zinc (II) would adsorb on kaolin from sincalang's deposit. Kaolin crushed and screened until the size solid approxiamettly - 200 + 240 mesh. Kaolin suspension prepared by rinsed witjh I M NaOH for approximately 12 hours. The solid included to Zn (II) solutions and determined AA (Atomic Adsorption Spectrometer). Samples were withdrawn every 15 minutes. The variables studied with temperature in the range 30 - 50 "C and concentration 40 - 60 ppm. The adsorpstion data analysed by the Frendlich, Langmuir and Brunauet ~ Emmet - Teller (BET) proposed models by regretionlinear method. Based on the result the freundlich model was suitable model to describe the equilibrium.From this model it was obtained that the value of constant equilibrium K = 2,6503 with temperature 3(fC, Enthalphi AH = -0,9865 kcal/mole ,Free energy Gibb AG =- 4,9007 kcal/mole and Entropy AS =12,918 kcal/mole	en_US
