Adsorption of surfactant modified bentonite Cr (VI) of
Degree is high, the bentonite C (VI) adsorption capacity and equilibrium between the solution concentration of less than 1 exponential power function . Bentonite adsorption mechanism and the microstructure of 3 closely related , yet after doing more research . Figure 5SDS soil on sorption isotherm of hexavalent chromium in Fig. 5Cr (VI) adsorptionisothermofSDS-bentonite Figure 61827 soil on sorption isotherm of hexavalent chromium in Fig. 6Cr (VI) adsorptionisothermof1827 a bentonite3 Conclusion 1),scarpe nike 2011, 1827 bentonite has strong absorption cr (VI) capacity , almost free from the influence of time and pH value , the average removal rate was 93%. 2) SDS soil adsorption of Cr (VI) was better than the original soil , but not as good as 1827 bentonite soil, the effect of adsorption of metal cations with the soil is almost 1827 , and far better than the original soil bentonite . 3) 1827 SDS soil and other soil and mechanism of adsorption is similar to belong to the Freundlich adsorption , and the soil is its special form in 1827 (n = 1), Q-C. Curve into a straight line , the correlation coefficient R = 0.9926. |
