十二烷基磺酸钠捕收红柱石作用机理研究

通过对吸附模型的量子化学计算,结合对实际吸附复合物的红外光谱分析,研究了十二烷基磺酸钠与红柱石的相互作用机理。计算结果表明:十二烷基磺酸根离子与红柱石作用时,会发生化学吸附,且十二烷基磺酸根离子将优先吸附在红柱石(001)面左侧的11号Al原子上;吸附反应过程中电子从红柱石表面的Al原子流向十二烷基磺酸根离子上的O原子。红外光谱分析在吸附复合物上发现了十二烷基磺酸铝的生成,证实了量子化学计算结果。

Collecting Mechanism Study on Using Sodium Dodecyl Sulfanate to Float Andalusite

Through quantum chemistry calculation method of absorption model, and in combination with the infrared spectrum analysis on the actual adsorption complex, the interaction mechanism between the sodium dodecyl sulfonate (SDS) and andalusite was investigated.The calculation results showed that the ion of sodium dodecyl sulfonate acted with the andalusite, resulting in the chemical adsorption.Moreover, the ion of sodium dodecyl sulfonate will be adsorbed optimally on the Al atom labeled 11.During the adsorption process, the electron from the Al atom on the surface of andalusite (001) will transfer to the O atom of SDS ion.The infrared spectrum analysis showed that aluminum dodecyl sulfonate was found on the absorption compound, thus verifying the results of quantum chemistry calculations.
