The palygorskite-sepiolite group of clay minerals has a wide range of industrial applications derived mainly from its sorptive, rheological and catalytic properties which are based on the fabric, surface area, porosity, crystal morphology, structure and composition of these minerals. For assessing potential industrial uses, the mineralogical and chemical composition of the clay and its basic ph...

this study aimed to develop techniques for purification of cyanotoxins dissolved in water -particularly those produced by microcystis aeruginosa species - using natural clay, chemically modifiednatural clay, commercial clay and ion exchange and adsorbent resins. except for natural clay, chemical pretreatment was required to increase the adsorption capacity of the treatment materials. all the cl...
