Abstract: The Na-bentonite compact with absorbent polymer was fabricated in order to observe their absorption and preservation about water. Absorption of fabricated specimens in the water and preservation of absorbed samples in the drying machine at 323 K was measured. It was obtained that the absorption had been increasing with inhancing absorbent polymer. Absorption of As-received Na-bentonite was lower than absorption of As-received absorbent polymer. The preservation had been also increased with absorbent polymer was obtained. Na-bentonite compact with absorbent polymer ware investigated the good absorption and preservation when the Na-bentonite compact with absorbent polymer 40 mass %.

Abstract: The Na-bentonite with contained smectite was fabricated in order to observe their absorption and preservation about water. Absorption of fabricated specimens in the water and preservation of absorbed samples in the drying machine at 323 K was measured. It was obtained that absorption had been decreasing with increasing smectite. Absorption of As-received Na-bentonite was higher than absorption of As-received smectite. The preservation has been also decreased with increasing smectite was obtained. Na-bentonite with contained smectite were investigated the good absorption and preservation when the Na-bentonite containing smectite 5 mass %.
