The Hibiscus extract Potential in Inhibiting Anodic Dissolution of Copper

Abstract:

Copper electro dissolution in H3PO4 acid is examined in solution containing different concentration of Hibiscus extract (Hibiscuss abdariffa). Potential of anode limiting current relation were computed and estimate of gently raising Hibiscus extract concentration (500-2000 ppm), The results reveal that Hibiscus extraction as a natural product has strong retardation behavior ranging from 24.5 - 42.1 % and the thermodynamic factors, adsorption isotherm and dimensionless parameters were given. Copper dissolution behavior in Hibiscus extract containing solution was investigated below ordinary convection and rotating cylinder electrode (RCE) as a compulsory convection. The rotating cylinder electrode RCE speed was investigated. The limiting current increases with increasing rotation, which indicates that the anodic corrosion is a diffusion-controlled process. The limiting current were reduced with raising extract plant concentration and raise with amplifying temperature from 293 -313 K). The activation energy values established which reaction rate was controlled via diffusion. Hibiscus extract adsorption follow Flory Huggins and kinetic thermodynamic models. The result at several circumstance was commanded via dimensionless correlations Sherwood (Sh), Schmidt (Sc) and Reynolds (Re) numbers.
