Differential pulse anodic stripping voltammetric (dpasv) technique for reactive black 5 analysis at glassy carbon electrode / Nur Aqilah Abdul Rahman

Dyes are generally defined as an aromatic organic compound which shows an affinity towards the substrate to which they are being applied. Dyes are used to give colour to fabrics. Hence, the amounts and contents of dyes that used in fabrics industry must be analyzed. The presence of dyes in wastew...
