Abstract
We investigated the use of chitosan for removing phenol oxide in the aqueous phase as a water-treatment process. We used p-quinone for the phenol oxide model material and investigated the capabilities of chitosan based on molecular weight (MW) and deacetylation degree (DD). We also examined reaction conditions (temperature and pH). The chitosan specifically removed p-quinone, rather than other phenols. The overall reaction rate constant was sufficiently high in the experimental range of 3.89 Ã 105 to 1.24 Ã 106 MW g molâ1 and from 83.1 to 88.6 DD%. Chitosan was suitable for separating p-quinone in the aqueous phase at basic pH levels. Activation energy was found to be 45 kJ molâ1.
