Environmental performance of two marine algae Ulva fasciata and Pterocladia capillacea in the biological treatment of four reactive dyes from aqueous solutions based on fresh and dried biomass

Abstract The runoff of textile dye effluents into public water bodies is a major environmental and health problem. Color removal, in particular, has recently become substantial scientific interest, as revealed by the multitude related research reports. present study focused on measuring efficiency two marine algae, Ulva fasciata Pterocladia capillacea, bio-removal four synthetic dyes (RY2, RR195, RB19, RB5) based fresh dried biomass tested algal species. According to highest removal efficiencies dyes, species were chosen from among nine different algae. Bio-removal was examined under effects salinity contact time. results this experiment that algae achieved high both saline water, but percentages higher compared conditions. percentage recorded after 8 h U. reached 82.75 83.23% for RY2 RR195 respectively. Contact time impact values obtained case fasciata, which impressive 100% RB195 RB5 P. capillacea had 91.11, 94.85 97.13% respectively, h. Our used highly significant biosorption most dyes.
