Phycoremediation of Thallium Toxic Metal Present in Gallery Water of an Abandoned Mine Area by Algae Cladophora fracta

In this study, phycoremediation of thallium toxic metal present in galery water of an abandoned mine area was investigated by using Cladophora fracta. Within the scope of the study, a reactor containing Cladophora fracta was used and it was determined whether the Cladophora fracta accumulated thallium depending on time. Additionally, the bioconcentration factor was calculated. According to research findings; the accumulations of thallium by Cladophora fracta, compared with uncontaminated alga, were 225% at 5 min, 450% at 10 min, 550% at 20 min, 575% at 40 min, 700% at 60 min, and 900% at 120 min, respectively. BCF values were between 1000-5000. This indicated that Cladophora fracta had bioaccumulation potential. As a result, this research carried out in mining area has documented the phycoremediation of thallium in gallery water of an abandoned mine area.
