Abstract
Developping chip and ecofriendlly corrosion inhibitors can replace toxic chemicals which are currently used in industries. Plant extract of Solanum surrattence in acetone, petroleum ether, and methanol has been tasted using mass loss and thermometric measurements for corrosion of aluminium in acid solutions. The plant extract of Solanum surrattence is a good corrosion inhibitor for aluminium. The inhibition efficiency depends upon the concentration of inhibitors, it inhibits the metal of 97.60% at its maximum value. This inhibitor shows efficiency at 25°C. At higher temperature the inhibition efficiency decreases. These types of inhibitors can be used to replace the toxic chemicals which are currently used in industries. We find out cheap and ecofriendlly corrosion inhibitors which can be used by acid, petrochemical, and chemical industries.
Highlights
Aluminium and its alloys lend themselves to many engineering applications because of their combination of lightness with strength, their thermal and electrical conductivities, heat and light reflectivity, and their hygienic and nontoxic qualities
We have investigated the effect of plant extract of Prosopis cineraria on corrosion of aluminium [3] and mild steel [4] in acid solution in our earlier communications
The present communication describes the influence of various concentration of the extract of Solanum surrattence on corrosion behavior of aluminium in acid media by mass loss and thermometric measurements
Summary
Aluminium and its alloys lend themselves to many engineering applications because of their combination of lightness with strength, their thermal and electrical conductivities, heat and light reflectivity, and their hygienic and nontoxic qualities. The corrosion of aluminium and its alloy in acid solutions have extensively been studied [1]. We have investigated the effect of plant extract of Prosopis cineraria on corrosion of aluminium [3] and mild steel [4] in acid solution in our earlier communications. The present communication describes the influence of various concentration of the extract of Solanum surrattence on corrosion behavior of aluminium in acid media by mass loss and thermometric measurements. Fresh berries contain [7] solasurine, 3,4-di hydroxy cinnamic acid, and caffeic acid Flowers of this plant yields [8] apigenin, quercetin-3-o-β-D-glucopyranosyl-o-βD-mannopyranoside (Figure 1). Roots expectorated of Solanum surrattence is useful in cough, asthma, and pain in the chest. Extract of the herb shows antiviral activity against Ranikhet disease virus and against sarcoma 180 in mice
