A Review on Algae Biosorption for the Removal of Hazardous Pollutants from Wastewater: Limiting Factors, Prospects and Recommendations

Algal biomass is a promising feedstock for carbonaceous adsorbents because of its rapid growth, high photosynthetic efficiency, and ability to thrive in wastewater and on non-arable land.

“Algal biomass has emerged as a promising feedstock for the production of carbonaceous adsorbents due to its rapid growth, high photosynthetic efficiency, and ability to thrive in wastewater.”

Climate change, characterized by rising global temperatures, altered precipitation patterns, and increased atmospheric CO2 concentrations, directly impacts biomass sources used as precursors in carbon material production, affecting growth rates and biochemical composition of algae and thereby altering carbon fixation efficiency and quality of resulting carbon materials.

“Climate change, characterized by rising global temperatures, altered precipitation patterns, and increased atmospheric CO2 concentrations, directly impacts the biomass sources used as precursors in carbon material production.For instance, variations in these environmental parameters may affect the growth rates and biochemical composition of algae, a critical feedstock, thereby altering both the ef”

Heavy metals and other pollutants are toxic and non-biodegradable, accumulate in tissues of flora, fauna, and humans, and cause severe health consequences such as central nervous system damage, dermatitis, cancer, kidney failure, and impairments to liver and reproductive functions.

“Given their toxic and non-biodegradable nature, these pollutants tend to accumulate in the tissues of flora, fauna, and humans, leading to severe health consequences such as central nervous system damage, dermatitis, cancer, kidney failure, and impairments to liver and reproductive functions [2].”
