Removal of chromium by two aquatic pteridophytes.

In the recent years, the use of phytoremediation for ameliorating metal pollution has been gaining ground. This study explores the. possibility of utilising two common aquatic ferns, Salvinia molesta Mitchell and Azolla rubra R.Br. for scavenging chromium from solutions. Chromium removal from spiked solutions ranged from 40-99% during the seven day exposure. Results reveal their bioremoval capabilities and potentialfor use in wastewater decontaminant
