Interactions of Sodium Dodecylbenzenesulfonate and Calcite in 0.55 M NaCl Solution

摘要

Complex mutual interactions of calcite and sodium dodecylbenzene sulfonate (NaDBS) were studied in 0.55 M NaCl solution, using several complementary techniques. Adsorption of NaDBS on calcite could be resolved from other proc- Esses such as adsorption onto the reaction vessel and/or formation Of soldi crystalline phases, when a special a. c. voltammetric proce- Dure was used below the critical micelle concentration (c.m. c.= =9×10~-5 mol/L).
