Three different spin-lattice relaxation times (T_1) of water were obtained in activated alumina-water slurry system, which indicate that there exist three states of water: bound water, pore water and bulk water. The chemical shift (δ_H) decreases as the amount of water added to the system increases due to the differences in contribution of these three states of water in the samples. The δ_H value for adsorbed water decreases nearly linearly and T_1 increases with elevating temperature, which result from the decrease in the content of bound water by the increase in thermal motion.
