Research and manufacture of high purity γ-Al2O3, applied as an adsorbent to treat Rhodamine B pigment

In the present study, γ-Al2O3 was fabricated from Tan Rai alumina hydroxide by some following steps: purifying hydroxitde HCl solution 5% to remove impurities, dissolving 25% obtain AlCl3 and then react with (NH4)2CO3 get AACH, decomposition of AACH at 500oC produce γ-Al2O3. After that, Sodium dodecyl sulfate (SDS) used modify surface increased area. The material will be removal Rhodamine B waste water.The study shown that modified has a large specific in water can completely treated pH = 7, adsorption time 20 minutes, concentration 10 ppm amount adsorbent is 5 mg/mL.
