Abstract

In the present study, γ-Al₂O₃ was fabricated from Tan Rai alumina hydroxide by some following steps: purifying alumina hydroxitde by HCl solution 5% to remove impurities, dissolving alumina hydroxitde by HCl 25% to obtain AlCl₃ solution and then react AlCl₃ with (NH4)₂CO₃ to get AACH, decomposition of AACH at 500^oC to produce g-Al₂O₃. After that, Sodium dodecyl sulfate (SDS) was used to modify g-Al₂O₃surface to increased the surface area. The material will be used to removal Rhodamine B from waste water.

The study shown that the modified γ-Al₂O₃ has a large specific surface area. The Rhodamine B in waste water can be completely treated by modified γ-Al₂O₃ at pH = 7, adsorption time 20 minutes, Rhodamine B concentration = 10 ppm with the amount of adsorbent used is 5 mg/mL.
