“…The marker dye usually has the chemical structure protected and only the manufacturer can detect it by specific methods. Neverthelees, some marker dyes are known in the literature and are commonly added to fuels with the purpose of control specific types of fuels, comprove the authentic, discourage robberies and adulterations, as well as control the distribution and use of some specifics fuels [93,94]. In Brazil, the adulteration of fuel has been a common problem, and the marked dyes are applied to distinguish the hydrated ethanol from the dehydrated ethanol.…”

Since 1856 when W. H. Perkin synthesized the first synthetic dye (Mauveine), a wide variety of colors and shades are produced and used in several commercial products. The occurrence in water and wastewater has gained controversy regarding their toxicity and mutagenicity and it has been regulation by several regulatory agencies. Thus, analytical methods able to determine these colorings in several matrices with high sensitive and robust enough are relevant. Among several analytical methods, the use of electroanalytical methods, especially the voltammetric techniques, are of great interest due to the high selectivity, sensitivity, use of low quantity of sample, little or without sample treatment, and low waste generation, which contributes to reduced environmental impact. Over the past decades, the technical based on current-potential curves by using of static electrodes have gained considerable progress, as minimizing the effect of capacitive current and the possibility of pre-concentration of the analyte at the electrode surface, which has reflected in lower detection levels. The present work gives an overview about the analytical methods available in literature focusing on electroanalysis of dyes by using voltammetric techniques. The advances of the electroanalytical techniques and the use of different modifiers to increase sensitivity and selectivity are reviewed.

“…Cardanol are also used for reducing brittleness and improving the flexibility of the blades (Blazdell, 2000). Both cardol and cardanol have been used in various applications such as adhesives, fuel additive (Suwanprasop et al, 2004;Vasapollo et al, 2011), plasticizing (Alexander and Thachil, 2010), cleaning, disinfectants, germicides and health care for workers (Prabhakaran et al, 2001). Seeds, nirmali (Srimurali et al, 1998) impregnated with zirconium coconut shell (Sathish et al, 2007) and clays have been used as adsorbents for the removal of fluoride from water (Alagumuthu and Rajan, 2010).…”

Anacardium occidentale L. is a tree native to Brazil, which is rich in phenolic lipids. Nowadays, the cashew bark (Cashew Nut Shell Liquid) has received great attention in the pharmaceutical industry, due to its economy, abundance and important chemical compounds. Net of cashew nut shell is classified according to the method of production of: (1) net of the shell of natural cashew nut (60-65% anacardic acid; 15-20% cardol and 10% of cardanol) and (2) liquid from the technical cashew nut shell (60-65% of cardanol, 15-20% cardol and 10% of polymeric material). This work aims to report the pharmacological properties of liquids from cashew nut shells. Results suggest that both liquids have antifungal, antibacterial, antiparasitic, anti-tumor, antiulcerogenic, molluscicides, antimutagenic and antioxidant activities. Natural cashew nut liquid is non-genotoxic, whereas technical liquid is genotoxic in prokaryotes and eukaryotes, although there is no evidence of their mutagenic effects on eukaryotic cells. In conclusion, the excellent antioxidant and non-mutagenic activities of cashew nut shell liquid (CNSL) provide opportunities for CNSL in the cosmetic and/or pharmaceutical industries, but continuous study is needed to allow safe and efficacious preparations.
