One of the plant that has potency as phytoremediator is (Limnocharis flava (L.) Buch) or also known as Genjer. The aim of this study was to determine the ability of genjer as phytoremediator of Cd (II), Cr (VI) and Pb (II) based on contact time (exposure period) variations (0, 3, 6 and 12) days. The concentration of Cd (II) and Pb (II) were analyzed by Atomic Absorption of Spectrophotometry (AAS) and Cr (VI) was analyzed using UV-Vis (UV Visible Spectrophotometry). The results showed that maximum absorption efficiency for Cd (II), Cr (VI) and Pb (II) were 83,70%; 43,98% and 90,31%, respectively (day 6). BCF (Bioconcentration Factor) result showed that Cd (II), Cr (VI) and Pb (II) value were > 1 (one). It is showed that genjer can be categorized as hyperaccumulator plant.otherAASgenjerphytoremediationUV-VISstudent Paper Post Degree
