The role of different carbonate salts on the interaction of anionic surfactant sodium dodecyl sulfate (SDS) with employed quinolone antibiotic drug (ciprofloxacin hydrochloride [CFH]) was explosively inspected through measuring specific conductivity (κ) of the investigated system. The drug, CFH, is an excellent antibiotic for the treatment of different bacterial infections like skin, urinary tract, and respiratory infections. The estimated critical micelle concentrations (cmc) of SDS were observed to be dwindled in the attendance of electrolytes and cmc reduction continues with the escalation of the electrolyte's concentration. The magnitudes of cmc for the SDS + CFH mixture were reduced with the elevation of temperature in K₂CO₃ and CaCO₃ medium while increased with the rise of the temperature in the Na₂CO₃ medium. The magnitudes of counterion binding to micelles (β) were increased with the increase of the concentration of Na₂CO₃ and K₂CO₃ up to definite value and then reduced with the increase of successive rise of concentration of both salts at all temperatures while decreased monotonically with the rise of electrolyte concentration in CaCO₃ medium. The values of standard free energy ( ) were achieved to be negative in each case suggesting spontaneous self‐assembly formation. The standard entropy change ( ) along with enthalpy change ( ) was also assessed and discussed elaborately.

碳酸盐电解质在不同温度下对喹诺酮药物与阴离子表面活性剂相互作用的作用：电导研究

通过测量所研究系统的比电导率（κ），爆炸性地检查了不同碳酸盐对阴离子表面活性剂十二烷基硫酸钠（SDS）与使用的喹诺酮抗生素药物（环丙沙星盐酸盐[CFH]）相互作用的作用。CFH药物是治疗各种细菌感染（如皮肤，泌尿道和呼吸道感染）的极好的抗生素。观察到SDS的估计临界胶束浓度（cmc）随电解质的增加而减少，并且随着电解质浓度的升高，cmc的降低继续。SDS + CFH混合物的cmc值随K的温度升高而降低₂ CO ₃和CaCO ₃中，同时与温度的以Na升高而增加₂ CO ₃介质。Na ₂ CO ₃和K ₂ CO ₃的浓度升高到一定值时，反离子与胶束（β）的结合强度增大，然后在两种温度下随着两种盐浓度的连续升高而减小。随着CaCO ₃介质中电解质浓度的升高单调下降。标准自由能的值（ ）在每种情况下都为负，表明自发形成自组装。还对标准熵变（ ）和焓变（ ）进行了评估和详细讨论。
