| description | In this article, basic physical and chemical properties and apparent performance of the reed biochar prepared under different temperature conditions are studied, and the change of the adsorption time with the change of time, initial solution pH value, initial solution Pb2+ concentration for three kinds of biochar have been studied. The main study results are given below, in the preparation of these three kinds of biochar, with the rise of temperature, the biochar productivity decreases, ash content increases and pH value increases. With the rise of pyrolysis temperature, the percentage of the C and N elements of reed biochar increases, while the percentage of O and H elements decreases. BET specific surface area, Langmuir specific surface area, T-plot microporous specific surface area, and BJH adsorption accumulative specific surface area have manifested L500>L700>L300. There is the law of L500>L700>L300 for the quantity of nitrogen adsorption by biochar. The adsorption experiment has shown the best adsorption effect of biochar L500 being prepared at 500°C, the optimal adsorption condition is pH6, the adsorption time is 150min, and adsorption temperature is 25°C. |
