摘要：
In this study, adsorption of phenol and p-chlorophenol (PCF) on metal-organic adsorbents, prepared by hydrolysis and subsequent condensation of acid-modified and unmodified Ti(OEt)(4), were investigated. Phenol and PCF uptake was related to adsorbate concentration, adsorbent's type, contact time, and temperature. The adsorption equilibrium of phenol and PCF on the prepared adsorbents was described by the Langmuir and the Freundlich models. It was observed that the adsorbents based on modified Ti(OEt)(4) were more effective for organics than the nonmodified counterparts. In addition, adsorption of PCF was greater than that of phenol on all adsorbent powders.
