发明名称 Process for the purification of inorganic salt containing organic material and purified salt for electrolysis of sodium chloride
摘要 An object of the present invention is to provide an effective and efficient process for the treatment of an inorganic salt containing an organic material which can solve various problems with the prior art, i.e., process for purifying an inorganic salt containing an organic material to an extent such that it can be recovered and re-used from the standpoint of environmental protection and utilization of resources. An inorganic salt containing an organic material is granulated or subjected to chemical treatment (mixed with an alkali and/or oxidizing agent), and then subjected to heat treatment so that it is purified.
