Using Cu2+solutions of different concentrations as objects,the hydrothermal biochar microspheres prepared based on agricultural wastes were used to adsorb and treat the Cu2+heavy metal solutions.The experiment studied the influence of adsorption time,solution concentration,and modification method on the adsorption effect of heavy metal Cu2+.The research results show that,citric acid modified biochar has better microsphere adsorption performance by comparing the adsorption effects of two different hydrothermal biochar microspheres on Cu 2+of heavy metal.
