The purpose of the matrix used to obtain activated carbon by chemical activation of the peach endocarp - Huayco Rojo variety, is to evaluate the adsorption capacity of mercury (II).The values obtained from the proximal analysis were 14.87% moisture content, 70.98% volatile solids, 6.22% ash and 7.92% fixed carbon, the highest yield observed was 41.4%.Four variables were considered in the adsorption tests, which were three activation temperatures (500, 600 and 700 °C), three different pyrolysis times (15, 30 and 45 minutes), two impregnation ratios (0.75 and 1.5 g H3PO4/g) and two different pH (2 and 7), likewise, the detection of mercury was by the Ditizone colorimetric procedure. The highest adsorption capacity corresponds to the treatment at 700 °C, 30 minutes of pyrolysis time, 1.5 g H3PO4/g of impregnation ratio and pH 2, reaching 19,465 mg.g-1for an equilibrium time of 150 minutes, observing that the most influential factor in the adsorption process was the pyrolysis time and the activation temperature. The kinetic model that presented a better fit was the pseudo second order, with a correlation coefficient close to 1 in the evaluated treatments. In the analysis of adsorption isotherms, the best fit was the model of the linear type isotherm.The comparison of the microphotographs of the electronic microscope between the activated carbon and the charcoal of the peach endocarp, it has been observed that the activation produces a greater degree of porosity.
