硫酰氟吸附的初步研究
The anion surfactant nals was the most efficient in the process and was selected as collector by orthogonal method. the interfacial tension and cmc of nals ( cmc 6. 5 10 - 3m ) in the solution was measured by hanging ring test, the function relationship between interfacial tensions and nals concentration was : = - 0. 9523 in 2c - 24. 534 in c - 81. 411. the relation of interfacial adsorption equilibrium in the solution system was respectively tested and calculated with gibbs equation and dynamic method. the conclusion showed that ( 1 ) the experiment result of dynamic method with was highly in coordination with the value which from theoretical calculation. ( 2 ) the surfactant molecule was in arrangement of monomolecular layer at the gas - liquid interface
