Influences of Biochar Aging Processes by Eco-environmental Conditions
Biochar is receiving increasing attention as a promising functional material in contaminated soil remediation.However,aging processes of biochar can usually take place and affect its remediation function,because surface properties of biochar are expected to change through a variety of biotic and abiotic processes.In this review,some important influencing factors of biochar aging processes were discussed,including temperature,and soil-physical,soil-chemical and soil-biological components.It pointed out that biochar aging processes may be promoted by high temperature,protected by soil components,particularly soil organic matter (SOM),and interactions with soil microorganisms.To further prolong application of biochar in nature,biochar aging can be mitigated by its influencing factors.
