Removal and uptake of copper (II) by Salvinia natans from waste water

The absorption of copper (II) from aqueous solution and from wastewater using Salvinia natans L., a free-floating plant growing abundantly in ponds and lakes in India, was investigated. The possible recovery of copper from waste streams using the plant was also studied. The maximal accumulation of c...

Description
Summary:The absorption of copper (II) from aqueous solution and from wastewater using Salvinia natans L., a free-floating plant growing abundantly in ponds and lakes in India, was investigated. The possible recovery of copper from waste streams using the plant was also studied. The maximal accumulation of copper took place within 24 h, and a maximal removal of 90 per cent of the copper present took place at concentrations below 50 ug per ml. Copper was successfully removed from waste water from acopper complex in Bihar State, India. The recovery of 96-98 per cent of the total metal absorbed by Salvinia was feasible.
