Abstract
The rapid growth of industrialization, particularly since the mid-20th century, has led to a significant increase in the discharge of heavy metals into aquatic and terrestrial ecosystems. Mine tailings and industrial effluents serve as major sources of toxic metals such as lead, chromium, mercury, cadmium, arsenic, and nickel, which persist in the environment and pose severe risks to human health due to their carcinogenic, neurotoxic, and bioaccumulative nature. Conventional remediation techniques, including chemical precipitation and ion exchange, are often costly, inefficient at low concentrations, and may generate secondary pollutants, thereby necessitating the development of sustainable alternatives.
Biosorption has emerged as a promising, eco-friendly, and cost-effective approach for the removal of heavy metals from contaminated environments, including mine tailings. This process involves the passive binding of metal ions to biological materials such as bacteria, fungi, algae, yeasts, and agricultural residues, facilitated by functional groups like carboxyl, hydroxyl, and amino groups present on cell surfaces. Both living and non-living biomass exhibit biosorptive capabilities, making the process versatile and scalable. Key factors influencing biosorption efficiency include pH, temperature, initial metal concentration, biomass dosage, and surface characteristics of the biosorbent.
