PROPERTIES OF ACTIVATED CARBONS DERIVED FROM DRY CONES PÍNUS SYLVÉSTRIS
Abstract
We have investigated the reception of activated carbons from waste softwood Pinus sylvestris by modifying the phosphoric acid followed by carbonization at 800 °C and high temperature steam treatment. The sorption properties of the material obtained with respect to copper ions (II). The structural features of the products obtained in the course of carbonization. It is shown that in the process of carbonization samples with additives H3PO4 at 800 °C, a porous material with a specific surface of 870 m2/g. It is found that the sorption capacity for iodine sorbent carbonized at 800 °C, is 128.68%. Also shown is that the resulting active carbons can be used in the purification of water from a copper ion (II), the kinetics of this process model is described pseudo-first order precedes sorption diffusion.
