Maximizing Adsorption Involving Three Solutes on Enhanced Adsorbents Using the Mixture-Process Variable Design.

ABSTRACT: Unmodified (UN), acid-treated (AT) and microwave-acid-treated (MAT) activated carbons were optimized for their solute removal efficacies by adjusting feed mixture compositions and process conditions. Acetaminophen, benzotriazole, and caffeine were used either individually or as binary/ternary mixtures in this study. The process conditions considered were the pH, adsorbent dosage, and type of adsorbent. Experimental responses such as total adsorbent loading (q _total) and total percentage removal (PR_total) were fitted with empirical models that had high adjusted R ² (>0.95), insignificant lack of fit (p-value > 0.22), and high model predictive R ² (>0.93). Mixture compositions of the feed were found to interact significa
