This study aims at development of desiccant filter for air-conditioning by using Wakkanai siliceous shale (WSS). To improve water adsorption ability of WSS, the chlorides was supported on WSS's surface. From the water adsorption isotherms, the amount of water adsorption of WSS supported with NaCI 5% solution increased to 120 mg/g, however that of the natural WSS was 25 mg/g at the relative humidity in the range from 40% to 70%. It was suggested that this improvement was occurred by the water transport into NaCI caused by capillary condensation of the water in the WSS pores. Furthermore, we confirmed that NaCI-supported WSS adsorbed moisture twice as much as natural WSS from the cyclic test.
