ANALISA PENURUNAN KADAR KLOR DENGAN MENGGUNAKAN ION EXCHANGER DAN KARBON AKTIF PADA AIR LAUT MARINA (Analysis of the Decline in Levels of Chlor Using Ion Exchanger and Activited Carbon in Marina’s Sea Water)

Abstract

Ion exchange is a method of processing units that consist of a chemical reaction between ions in the liquid phase with the ion insoluble solid media (resin). Chlorine content analysis was conducted by titration called titration Argentometry. Titration is performed using a solution of AgNO3 titrant (Silver Nitrate) with indicator titration is K2CrO4 (Potassium chromate). Sea water contains 3.5% salts, dissolved gases, organic materials and insoluble particles. The main salts contained in seawater is chloride, sodium, sulfate, magnesium, calcium, potassium and the rest teridiri of bicarbonate, bromide, borax acid, strontium and fluoride The most substantial decrease in chlorine content occurs in the variable valve aperture 1/3, this is because the water that comes into the column has a longer contact with the resin for column flow over flow, so more and more exchange of metal ions in water with ions in resin and the less the water that can conduct electricity.
