Adsorption of Copper Ion from Acidic Wastewater by Local Natural Zeolite

Natural zeolites are available in Indonesia very large quantities and the market at affordable prices. The use of zeolite has developed various fields industry, water treatment wastewater treatment. study on ability local natural to adsorb copper from acidic a laboratory Tangerang been conducted. XRD data show that consists mordenite as main mineral quartz an accessory mineral. Acid activation with HCl 3 M could remove impurities based data. Mordenite is one most abundant minerals commercially used for many purposes including adsorbents, catalyst, fertilizer, gas separation. crystallinity decreases throughout process acid calcination. calcined better adsorption compared without any optimum percentage 14.554% solution pH 0.3 by using 10 grams 200 mL solution.
