“…The removal efficiency decreased with the augmentation of pH to neutral, and also in alkaline media. Similar data are disclosed by other papers which reveal that acid conditions are suitable for the adsorption of this type of dyes [ 67 , 68 ].…”

“…After carbonization (CDC) and activation (BMCDs), BMCDs still exhibited a diffraction peak within the range of 10°–30°. This may be assigned to the plane of graphite structure (002), indicating that BMCDs had a classic local-order structure of carbon materials [ 9 , 11 ]. The intensity of this peak was weak and it was a broad peak, which can be explained by the fact that BMCDs contained both crystalline and amorphous structures [ 9 , 11 ].…”

“…This may be assigned to the plane of graphite structure (002), indicating that BMCDs had a classic local-order structure of carbon materials [ 9 , 11 ]. The intensity of this peak was weak and it was a broad peak, which can be explained by the fact that BMCDs contained both crystalline and amorphous structures [ 9 , 11 ]. Like many dung-based biochars [ 18 , 19 ], there are many irregular but distinct peaks, which can be explained by the inorganic salts (e.g., sodium chloride), bone meal, and shell meal, which were fed in the process of animal husbandry, connected to the carbon matrix during high temperature pyrolysis.…”

“…Moreover, substituting Equation (8) into Equation (9) and undergoing a simple transformation can give Equation (10) [ 42 ]: where K d is the distribution constant, Q e (mg/g) represents the adsorption capacity at equilibrium, C e (mg/L) is the equilibrium concentration of the Cr(VI), R stands for gas constant (8.314 J·mol −1 ·K −1 ) and T (K) is the absolute temperature.…”
