Abstract
Caragana Korshinskii Kom were charred to yield the biochar in the temperature of 200℃, 300℃, 400℃ and 600℃. The components of Caragana Korshinskii Kom biochar were analyzed, the structure was surveyed through SEM and the adsorption isotherm curve was plotted with the specific surface area analyzer. The pore volume, size, and specific surface area were calculated. Biochar were mixed into soil column to detect the adsorption ability to diuron herbicide. The results showed that the adsorption isotherm curves of Caragana Korshinskii Kom biochar were the traditional I adsorption curves, the productivity of biochar decreased with the raising of charring temperature. Biochar, charred at the temperature of 600℃, had achieved 44.71% of yield rate of carbonization, 187.56 m2·g-1 specific surface area and mean 4.83 nm pore size. The microspore volume account for 53% in total pore volume. 1% of biochar had the significant effect on adsorption of diuron in soil, 3% of biochar in soil reached an optimal application amount balancing between its properties and cost.
