MEASUREMENT OF ADSORPTION CAPACITY OF HEAT RESISTANT ADSORPTION MATERIAL FOR TREATMENT OF HIGH TEMPERATURE WATER

摘要

PURPOSE:To measure the adsorption capacity of a number of heat resistant adsorption material simultaneously with a handy operation, by heating the heat resistant adsorption materials, metal or a compound containing an element the same as the metal ion to be adsorbed and water in the same container. CONSTITUTION:An oxidized metal foil 9, a heat resistant adsorption material 4 and water is fed into a quartz container 10 through a sealing section 11 opened. Then, the container 10 is made vacuum by evacuation through the sealed section 11 and then, the sealing section 11 is sealed up with a gas burner. After the quartz container is sealed up, it is held in an autoclave with water and heated with a heater 14 upto a specified temperature to get metal ion adsorbed on an adsorbent 4. The measurement of the adsorption capacity is done by chemical analysis on the adsorbent 4 after the end of the adsorption. This enables the measurement of the adsorption capacity of metal ion in a short time by such a handy method that the adsorbent 4 and a metal oxide 9 as adsorption source of metal ion to be eluted are placed in the same container 10 and then, heated only.
