Abstract

This study aims to determine the juice of tamarind (Tamarindus indica L.) in reducing levels of heavy metal mercury. Tamarind juice was tested by phytochemical screening to determine secondary metabolite compounds in tamarind juice so that it can be used to reduce levels of mercury. Determination of mercury levels by means of tamarind juice added a metal simulation of mercury 10 ppm which is read on atomic absorption spectrophotometry at a wavelength of 253,7 nm. Determination of the reduction in mercury is done by using a series of concentrations of tamarind juice of 0,5%, 1%, 1,5%, 2% and 2,5%. The results showed positive tamarind juice containing active compounds of citric acid, flavonoids, alkaloids, saponins, and steroids and produced an average concentration value that could reduce mercury up to 50% (EC50) by 2,3% with coefficient of variation 0,22%.
