Effect of pH on dienestrol adsorption by coconut shell biochar
The effect of solution pH on adsorption of dienestrol (DS) by coconut shell biochar (CSB) was investigated. The optimum solution pH was 5. This suggested that the strong chemical interaction of DS with the CSB. Therefore, CSB, as a green, environmental-friendly adsorbent, can be applied to the adsorption of contaminants in environment.
