Comparative Study of Corrosion Inhibition In Carbon Steel Using Non Ionic Surfactants In Acidic Medium
Abstract: The use of surfactants is one of the numerous ways of protecting a metallic surface from electrochemical oxidation or corrosion. The amphiphilic nature of these surfactants leads to the formation of a protective layer on the metallic surface, effectively minimizing the area of contact between the fluids and the metal, thus inhibiting corrosion. Cationic surfactant like CTAB (Cetyltrimethylammonium bromide) has been most commonly used as a corrosion inhibitor, but since …

Fluoride Distribution and Related Health Problems
Abstract: Fluoride is one of the very few chemicals that cause significant effects in people depending upon their concentration. Although present naturally in soil, water and air, fluoride consumption occurs largely through water. Fluoride intake at low concentration is known to cause beneficial effects on teeth, however at high concentrations; it may give rise to a number of adverse effects. These range from mild dental fluorosis to crippling skeletal fluorosis as …
