STUDI FITOREMEDIASI LOGAM TIMBAL (Pb) DAN KADMIUM (Cd) OLEH TANAMAN KAYAMBANG (Salvinia molesta)

Study phytoremediation of lead (Pb) and cadmium (Cd) by kayambang plants (Salvinia molesta) has been studied. This study assessed the ability of plants to absorb Pb and Cd which is influenced by the addition of various metal and NPK fertilizer on the medium containing the test solution. Samples of plants were interacted with NPK fertilizer, Pb and Cd. The variations of  NPK 1 mg/L, I,5 mg/L, 2,5 mg/L and 10 mg/L and the variations of Pb (100 mg/L, 400 mg/L and 800 mg/L) and cadmium (50 mg/L, 100 mg/L and             200 mg/L). Optimum pH for growing the Kayambang plants (Salvinia molesta) is a range pH of 6-7. Observations were made every 7 days until the day of 35th, by measuring levels of…
