Natural Clinoptilolite Based Solid-State Compositions for Low-Temperature Air Purification from Sulphur Dioxide

Abstract:

Natural clinoptilolite (N-CLI) and N-CLI based solid-state compositions containing copper(II) chloride and halide ions (X^-= Cl^-, Br^- or I^-) were investigated by X‑ray diffraction phase analysis, IR spectroscopy, thermogravimetry, water vapour adsorption, and pH‑metry. After that, they were tested in the reaction of low-temperature sulphur dioxide oxidation with air oxygen. It has been found that N-CLI has no protective properties in respect of sulphur dioxide whereas CuCl₂‑KX/N-CLI compositions have the significant protective activity in the process of air purification from sulphur dioxide increasing in the order Cl^- < Br^- < I^-.
