Deodorizing paper using ß sepiolite

ß-sepiolite was combined with pulp using special additives to make hand¬ made paper. Two kinds of ZM-clays containing ß-sepiolite, occurring in the Sivirihisar region of Central Anatolia, Turkey, were used for this paper making : a white one of low purity and a brown one of high purity. As ß-sepiolite content increased, the ammonia-adsorbing power of the paper increased. The apparent adsorption isotherm shows a sharp increase of water vapor adsorption at relative humidities above 90%. Machine-made paper containing about 60% white ZM-clay, or about 39% ß-sepiolite, can be called deodorizing paper, because it can adsorb almost any unpleasant odorants in our environment such as ammonia, isovaleric acid, methylmercaptan, nitrogen dioxide, ozone, pyridine and trime thy lamine.Sugiura Masahiro, Horii Mitsumasa, Hayashi Hiroaki, Suzuki Takatoshi, Kamigaito Osami, Nogawa Shoichi, Oishi Shiro.
