Amino modified eucalyptus biochar (ABC) was prepared from eucalyptus biochar by amino amendment with ammonia, concentrated nitric acid, concentrated sulfuric acid and sodium dithionite. The preparation parameters of ABC were optimized by orthogonal experiment. It was found that the optimal preparation process of ABC was: carbonization temperature was 300°C, volume ratio of nitric acid to sulfuric acid was 2:1 and the consumption of ammonia water was 15 ml. The results of characterization indicated that the morphological structure of ABC changed, and the amino functional group was successfully loaded on the surface of the biochar.
