Abstract: As raw materials, the natural zeolite was mixed with powder coal and bentonite.And then the mixture was produced into zeolite granular adsorbent by shaping, low-temperature drying and high temperature calcination, which was used to absorb Cationic brilliant red solution.The property of the sample was measured, and the effect of calcination temperature, absorbing time on adsorption reaction was discussed.The experiments indicated that the granular absorbent is possessed of low loss ratio and fine absorption ability for Cationic brilliant red with the mass proportion of the zeolite, bentonite and powder coal of 20∶3∶3 after calcinations at 650 ℃.The sample can be well repeatedly applied.

Key words:  Zeolite granular absorbent, Calcination temperature, Absorption
