Potensi Tanaman Genjer (Limnocharis Flava (L.) Buch) Sebagai Fitoremediator Ion Kadmium (Ii), Kromium (Vi) Dan Timbal (Ii)
SUMMARY
Phytoremediation is cost-effective and environmentally technology that use plants to clean up the environment. 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 (Limnocharis flava (L.) Buch) as phytoremediator of cadmium (II), chromium (VI) and lead (II) based on contact time (exposure period) variations (0, 3, 6 and 12) days. The concentration of cadmium (II) and lead (II) were analyzed by Atomic Absorption of Spectrophotometry (AAS) and chromium (VI) was analyzed using UV-Vis (UV Visible Spectrophotometry). The results showed that maximum absorption efficiency for cadmium (II), chromium (VI) and lead (II) were 83,70%; 43,98% and 90,31%, respectively (day 6). BCF (Bioconcentration Factor) result showed that cadmium (II), chromium (VI) and lead (II) value were > 1 (one). It is showed that (Limnocharis flava (L.) Buch) can be categorized as hyperaccumulator plant.
