Technical Field The present invention relates to a method for the removal of dissolved inorganic and organic impurities from water, and more particularly, to a method for the removal of the dissolved inorganic and organic impurities from water using ferric carbonate as a adsorbent. 2. Background Art The use of iron for the purification of water is not entirely new. For example, in U.S. Pat. No. 2,911,029, a filtration system for purifying contaminated water using an iron compound, such as ferric sulfate, are disclosed. More recently, in U.S. Pat. No. 5,324,555, iron(III) chloride and iron(III) oxide based oncopolymers are used to remove organic pollutants in waters. The iron adsorption, as well as, other methods of removing suspended and dissolved contaminants from water require the presence of sufficient quantities of adsorbent. The amount of adsorbent required to remove one gram of dissolved organic carbon, for instance, is about 0.5 grams of iron. As such, it is not surprising that iron compounds are often discarded because they contain iron. Iron compounds are characterized as having a very high specific surface area, and for this reason, they are often used as catalysts for the conversion of toxic chemical compounds in waste streams. See for example, U.S. Pat. No. 5,246,479 which describes the use of iron and copper oxides in a catalytic converter in an automobile exhaust system to remove hydrogen chloride from the exhaust. Because iron is oxidized to iron(II), the iron is unavailable to adsorb the contaminants. Other methods of removing the iron contaminants in the waste stream require the addition of carbon to the waste stream. This method is described in Japanese patent number 5-201,918. When too much iron is removed, the remaining carbon is reduced to carbon monoxide. When too little iron is removed, the carbon is oxidized to carbon dioxide, while the iron is reduced to an iron-carbon compound. The composition of the impure water is well known and includes water, high concentrations of magnesium, calcium, and manganese, etc., and is one of the major problems faced in the treatment of waste water. Other problems arise when the waste stream containing contaminants is toxic, such as cyanide and acid gases. The techniques and materials to remove these materials from waste waters are well known in the prior art and are not addressed in the present invention. On the other hand, iron and other metals are desirable for use in desalination processes. U.S. Pat. No. 3d9ccd7d82
