文摘
- •
The inhibitor efficiency increases with increase in ciprofloxacin concentration.
- •
Polarization measurements show that ciprofloxacin acts as a mixed type inhibitor.
- •
The adsorption of the inhibitor on copper surface follows Langmuir adsorption isotherm.
- •
The negative values of ΔGads indicates that the adsorption is spontaneous and exothermic.
