The Effectiveness of Arthrospira platensis for the Purification of Copper-Contaminated Water

The presented work is devoted to the study of the ecological potential of Spirulina Arthrospira platensis to absorb copper ions from the water polluted by given heavy metal. The obtained data reveal the ability of Spirulina in a short time, in particular for 3 days to diminish 70% of Cu 2+ ions of the initial incubation medium (100 ppm). The physiological parameters of Spirulina under the influence of copper on algae were also studied the highest concentration of Cu 2+ ions cause inhibition of biomass accumulation by 15% and decrease of chlorophyll content by 30%. The presented results underline the capacity of Arthrospira platensis for the purification of water contaminations by copper.
