Tóm tắt

 This report shows research results of adsorbability of Cr(VI) and Ni(lI) of Cao Bang manganese ore as adsorbent desiccant. Experiments were done with the following parameters: the mass of absorbent desiccant: 1.0g
  the volume of Cr(VI) or Ni(lI) solution: 25mL
  shaking speed: 200 rounds/minute
  time to reach adsorption equilibrium of both above ion were 90 minutes at room temperature (25 +/- 1°C. The best adsorption pH for Ni(lI) was 5 - 5.5, for Cr(VI) was 2.0. The result shows that, the adsorption according to model Langmuir adsorption isotherm, the maximum adsorption capacity of Cao Bang manganese ore for Cr(VI) was 1.692 mglg and for Ni(lI) was 1.845 mg/g.
