Preparation and Characterization of Nano-Strontium Titanate Based on Glass Fiber Filter and its Application in Adsorption of Heavy Metals

Abstract:

Nano-strontium titanate based on glass fiber filter (GFST) was successfully prepared by sol-gel method and characterized using XRD and SEM. The adsorptive potential of GFST for heavy metal ions, such as lead, cadmium, zinc and nickel, was investigated. The results showed that the nano-strontium titanate could crystal based on glass fiber, gaining a new block adsorbent like a leaf. The lead, cadmium, zinc and nickel ions were quantitatively retained at pH 6-9; their adsorption capacities of GFST for lead, cadmium, zinc and nickel ions were 153.21 mg•g-1, 8.32 mg•g-1, 21.36 mg•g-1 and 4.80 mg•g-1, respectively. The adsorbent can be regenerated completely by elution with 0.5 mol•L-1 HNO3. The adsorbent has a promising prospect in removal or enriching of lead, cadmium, zinc and nickel ions in water.
