Polyethylene glycol removal from water
WebThe zeolite particles were isolated by the alkaline extraction method from coal fly ash using a multistep process. The sodium silicate solution obtained from this process was used as a silica-aluminum precursor to synthesize zeolite via a sol–gel method using polyethylene glycol (PEG) as the surfactant and sulfuric acid as the catalyst.
