The aim of this study was to evaluate the larvicidal activity of <strong>C</strong>ashew <strong>N</strong>ut <strong>S</strong>hell <strong>L</strong>iquid (CNSL) against the <em>Culex quinque fasciatus</em> in larval stage. The CNSL was diluted in water by addition of aqueous extract of <em>Sapindus rarak </em>DC to increase its solubility. Larvae were exposed to varying concentrations of that mixture. The larvae mortality was observed after 24 h exposure. LC<sub>50</sub> and LC<sub>90</sub> value by extrapolation were 20,52 ppm and 55,41 ppm respectively. CNSL were specified by characterizing its physico-chemical properties and  anacardic acid as marker compound by High Performance Chromatography (HPLC). The results were the mixture of Cashew Nut Shell Liquid (CNSL)<strong> </strong>and Aquous extract of S<em>apindus rarak </em>DC had larvicidal activity against <em>Cx. Quinque-fasciatus </em>and further investigations were needed to identify the fatty acid derivative as active compound of CNSL which  responsible for larvicidal activity.

Abstract Background Cashew nut shell is a by-product of cashew (Anacardium occidentale) production, which is abundant in many developing countries. Cashew nut shell liquor (CNSL) contains a functional chemical, cardanol, which can be converted into a hydroxyoxime. The hydroxyoximes are expensive reagents for metal extraction. Methods CNSL-based oxime was synthesized and used to extract Ni, Co, and Mn from aqueous solutions. The extraction potential was compared against a commercial extractant (LIX 860N). Results All metals were successfully extracted with pH0.5 between 4 and 6. The loaded organic phase was subsequently stripped with an acidic solution. The extraction efficiency and pH0.5 of the CNSL-based extractant were similar to a commercial phenol-oxime extractant. The metals were stripped from the loaded organic phase with a recovery rate of 95% at a pH of 1. Conclusions Cashew-based cardanol can be used to economically produce an oxime in a simple process. The naturally-based oxime has the economic potential to sustainably recover valuable metals from spent lithium-ion batteries. Graphic abstract
