Fig. 2From: A new simple method for determining the critical micelle concentration of surfactants using surface plasmon resonance of silver nanoparticlesThe SPR spectra of AgNPs at different pHs in the presence of CTAB (a), TX-100 (b), and SDS (c). Conditions: 2.0 mL AgNO3 (2.0 × 10−3 mol L−1), 1.0 mL NaBH4 (1.0 × 10−2 mol L−1), 1.0 mL of 1.0 × 10−3 mol L−1 surfactant and 25 °CBack to article page
