Abstract
Heavy metals were analyzed in various samples of waste water from a metal plating factory in Istanbul. Chromium, copper and nickel uptake from industrial wastewater by water hyacinth (Eichhornia crassipes) at different dilution was examined by AAS and UV‐visible spectrophotometric methods. The results were statistically compared by t‐ ad F‐ tests. Since heavy metals are effectively removed, water hyacinth may be used for wastewater purification after dilution or as a step of wastewater treatment unit for industrial effluents under conditions in Turkey.
