Comparison Of Heavy Metal Absorption Of Some Algae Isolated From Altınapa Dam Lake (Konya)

Abstract

Today, due to the intense pollution in water resources, clean water shortage is experienced in most regions. In order to remove the pollution from waters, many studies are carried out using algae with high metal absorption capacity. In our study, benthic algae samples from different habitats (epipelic, epiphytic and epilitic) were taken from the Altınapa Dam Lake in Konya, in order to study the potentials of heavy metal removal. Some microalgae were isolated from the samples and heavy metal absorption capacities were examined among the pure cultures obtained. Biosorption properties were tried to be determined in samples taken at 5, 10, 20, 45, 60, 90 and 120 minutes by exposing Chlorochytrium paradoxum, Haematococcus lacustris and Scenedesmus circumfusus species to heavy metals of Cu and Mn. Scenedesmus circumfusus species reached the best absorption capacity for both Cu and Mn metals. According to this research, the algae we studied are of the opinion that they can be used to increase the efficiency and selectivity of heavy metal biosorption.
