Abstract

According Eckenfelder, (1989), the presence of iron in the earth's crust was thefourth biggest. Iron is found in the form of cation ferrous (Fe 2+) and ferric (Fe 3+). In the natural waters with a pH of about 7 and a dissolved oxygen sufficient ferrous ions which are soluble oxidised to the ferric ion. This oxidation occurs at the release of electrons. On the contrary. the reduction of ferric into ferrous electron capture occurs. Iron oxidation and reduction process does not involve oxygen and hydrogen. Iron concentrations in the groundwater ranged from 0.01 mg / 1 up to ± 25 mg / 1. If the concentration of iron in the water is relatively large, will give a flavor to the water that describe the taste metallic, astringent, or even drugs can cause toxic effects. Ion exchange resin is a polymer having a particular group. Basically the ion exchange resin was divided into 2 types of cations and anions, where the ability of the ion exchange process is influenced by many parts of the active ingredients contained in the resin and the ion exchange capability. The concentration of the active site and the ability of a resin ion pernukaran usually contained in the resin properties. Ion exchange is a physical-chemical process. In the process of the insoluble compounds, in this case the resin accept certain positive or negative ions from solution and releasing other ions in the solution is the same equivalent amount. If the ions are exchanged in the form of a cation, then the resin is called cation exchange resin, and if ions are exchanged in the form of anions, eat resin is called ion exchange resin anion.Rangkaian tool exchanger consists of three tanks, the tank cation exchanger, anion exchanger tank, and activated carbon tanks, each of which is made of FRP. At the top of the tank there is a way valve to the filter, fast rinse and back wash. The method used in the analysis of Fe content is permanganometry a titration method using potassium permanganate, a strong oxidizing agent as titrant. Titration is based on titration of reduction and oxidation, or redox. In this lab to test the Fe content is done by means of Ion Exchangers, with as much as 100 liters of water each variable. The variables used are the valve 1/3, 2/3, and 3/3. Time used for 30 minutes and take 15 ml of the sample in the tank cation, anion active and more carbon. Results of observations obtained in the Fe content of the variable aperture 3/3 tank of cations, anions, activated carbon of 0.177%; 0.173%; 0.167%. At 2/3 variable of 0.15%; 0,142%; 0.123%. And the 1/3 variables of 0.11%; 0,084%; 0.074%. It can be concluded that the greatest reduction in Fe content occurs at the smallest aperture or variable valve 1/3 (Contents of Fe, Ion Exchangers, permanganometry)
