REMOVAL OFCHROMIUM FROM INDUSTRIAL WASTEWATER USING BARDI LEAVES

Abstract

In this researchBardi leaveswere used which are available in high quantity in Iraq to remove Chromium (VI) from wastewater that is considered as an environmental pollution . The experiments were conducted by batch adsorptionsystem..The investigation studied the influenceparameter ( pH , time ,and initial concentration of adsorbent material ). The adsorption efficiency was tested by dissolving Potassium di chromate which is contaminated with milled Bardileaves.The removal efficiencies of (90-95% ) were obtained for pH( 2 – 3 ) and duration time ( 3 – 4 ) hours respectively. All tests were conducted by (UV/VIS spectrophotometer (Model UV-9200)).
