Surface‐enhanced Raman analysis of vitamin B complex: Quantitative detection of p‐aminobenzoic acid


Journal Article

Surface‐enhanced Raman scattering (SERS) spectra of vitamin B complex extracted in ethanol were analyzed using a silver‐coated alumina substrate. The SERS effect appears to enhance selectively the spectrum of p‐aminobenzoic acid (PABA) from among the complex constituents of the vitamin B complex tablet. A calibration graph of SERS signal intensity versus concentration of PABA was constructed for quantitative analysis. With such a graph it is possible to detect PABA down to low parts per million levels. The potential of the SERS technique in other analytical and biomedical areas is discussed.
