Abstract

Modified carbon paste electrode (CPE) by cobalt hexacyanoferrate (CoHCF) was prepared and the sensitivity of the prepared electrode was analyzed by differential pulse voltammetry. The electrochemical behavior of methylene blue on cobalt hexacyanoferrate modified carbon paste electrode (CoHCF / MCPE) has been investigated by differential pulse voltammetric technique. Also the detection limit of modified electrode was investigated on methylene blue dyes from textile industrial waste water. By the prepared electrode 1.222×10-4 M, 1.214×10-4 M and 1.217×10-4 M Methylene blue was detected in the textile effluent at three sample sites and 100.5 to 104.5 % of recovery was calculated. The prepared and modified electrode was efficiently detects 1.053 x10-6 limit of detection.
