Abstract A novel modified sensor based on electropolymerization of hippuric acid (HA) using cyclic voltammetry within the potential window − 1 to 1.5 V for 10 cycles at a scan rate 100 mV s −1 over multiwalled carbon nanotubes (MWCNTs) battery graphite electrode (BGE). Poly (HA)/MWCNTs/BGE exhibited two linearity ranges 3.00 × −3 1.00 µM (5.29 −4 – 0.18 µg/ml) and 5.00 3 (0.88− 176.22 with limit detection (LOD) 0.06 −2 (1.06 quantification (LOQ) 2.00 (3.52 µg/ml). The poly was successfully applied determination SER in presence tryptophan human blood serum recovery 98.31–105.47% RSD values 3.02– 4.77%. Green chemistry metrics : national environmental index (NEMI), analytical greenness metric (AGREE), Raynie Driver, green procedure (GAPI), eco-scale were employed indicated that proposed can be classified as an excellent method, achieving score 84.
