摘　　要：以育菇菇渣为原料,采用碳酸氢钠为活化剂制备菇渣基生物炭,研究了不同原料比、活化温度制备的生物炭吸附恶霉灵的性能,并进一步考察了载药生物炭的缓释过程。结果表明,原料质量比为1∶2,700℃下保温2 h是制备菇渣生物炭的最佳条件;在中性和弱碱性环境中更利于发挥菇渣生物炭对恶霉灵的缓释效果。In this study, mushroom residue was used as raw biomass material, and Na HCO3 was used as activating agent to prepare porous biochar. The effects of different ingredient ratio and activation temperature on the adsorption performance of the biochar towards to hymexazol were studied by single factor experiment, also the slow-release process of the drug-loaded biochar was investigated. The results showed that the mass ratio of raw materials was 1:2, and the activation temperature was set to 700℃ were optimum condition to prepare biochar, as well as neutral and weak alkaline environments were favorable for the slow release of hymexazol from the drug-loaded biochar.
