摘要

The ZnO-CA nanocomposite film was fabricated using solution casting method. The crystalline nature of the nanofilm was characterized using x-ray diffraction technique and surface morphology was studied by using scanning electron microscopy. The factors affecting Cd (II) ion adsorption in a batch mode were studied including the solution pH, and contact time for determining removal efficiency. The adsorption isotherm could be described well with Langmuir. The maximum monolayer adsorption capacity for the removal of Cd (II) ions was found to be 104.36 mg/g. This shows that, this fabricated nanofilm is capable for using in real time application.
