WebMechanisms of biochar adsorption. In adsorption, the adsorbate is associated with the adsorbent's surface until equilibrium is achieved. The steps involved in the adsorption … WebDec 17, 2008 · The determined complexation capacities were negatively correlated to the deposition time, which could be described using empirical equations. The true values of the complexation capacities were then calculated by extrapolating the deposition time to zero. The procedure developed was applied to a fresh water sample from Pond Weiming, Beijing.
