EFFECTS OF PRETREATMENT ON PHYSICAL AND ION EXCHANGE PROPERTIES OF NATURAL CLINOTILOLITE

摘要

Four pretreatment procedures have been applied to natural clinoptilolite to establish the influence of the pretreatment process on the properties of the material under investigation. Modification of material properties is imposed for its use in wastewater treatment via ion exchange processes. Batch pretreatment procedures as well as continuous flow column have been studied by using sodium chloride, sodium hydroxide and nitric acid solutions in deionized water.
