Pengaruh Kerapatan Bioijuk Terhadap Penurunan Logam Berat Pb Dan Cd Yang Terk…

The Sail River is one of the Siak watersheds contaminated with heavy metals Pb and Cd. This study aims to determine the decrease in heavy metals Pb and Cd in water due to the use of different bioijuk densities. The study was conducted in March-April 2019. This study used a completely randomized design (CRD), with 3 different bioijuk density treatments, namely P1 (rare density), P2 (medium densi…
