A clear insight into the affinity of biochar towards water is critical for its intended application. The state of the biochar would govern its use for a particular application. For example, hydrophilic biochar is preferred when sorption or organic contaminants are concerned. It is, at present, not clearly established the factors that govern the hydrophilicity and/or hydrophobicity of a biochar. Comprehension of the factors that affect the affinity of biochar towards water would aid to create ...
