Adsorption of copper(II) in biochar-humic acid–water system

Abstract Both biochar and humic acid adsorb heavy metals, but their combined effect has rarely been reported. In this paper, the adsorption of Cu(II) by single biochar (BS) and biochar with humic acid (BS + HA) in aqueous solution were studied, and the effects of solution pH, initial Cu(II) concentr...
