This article explores recent advancements and innovative strategies in biosorption technology, with a particular focus on the removal of heavy metals, such as Cu(II), Pb(II), Cr(III), Cr(VI), Zn(II), and Ni(II), and a metalloid, As(V), from various sources. Detailed information on biosorbents, including their composition, structure, and performance metrics in heavy metal sorption, is presented. Specific attention is given to the numerical values of the adsorption capacities for each metal, showcasing the efficacy of biosorbents in removing Cu (up to 96.4%), Pb (up to 95%), Cr (up to 99.9%), Zn (up to 99%), Ni (up to 93.8%), and As (up to 92.9%) from wastewater and industrial effluents. In addition, the issue of biosorbent deactivation and failure over time is highlighted as it is crucial for the successful implementation of adsorption in practical applications. Such phenomena as blockage by other cations or chemical decomposition are reported, and chemical, thermal, and microwave treatments are indicated as effective regeneration techniques. Ongoing research should focus on the development of more resilient biosorbent materials, optimizing regeneration techniques, and exploring innovative approaches to improve the long-term performance and sustainability of biosorption technologies. The analysis showed that biosorption emerges as a promising strategy for alleviating pollutants in wastewater and industrial effluents, offering a sustainable and environmentally friendly approach to addressing water pollution challenges.

The research focuses on examining the biosorption capability of raw mixed seaweed biosorbent (RMSB) for the removal of the hazardous metal cadmium (II) under controlled environmental conditions. Using techniques such as elemental dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR), biosorbent was characterized. The impacts of adsorbent dosage, contact time, initial Cd concentration, pH, and temperature have been assessed for the removal of Cd (II) and its adsorption. Optimum levels - pH, biosorbent mass, contact duration, and temperature were 5, 2 g/L, 50 minutes, and 303 K, respectively. The optimum intake of metals Cd (II) has been evaluated with isotherm modeling. Single-layer sorption was confirmed by the Freundlich isotherm, which proved to be an excellent fit. Maximum potential adsorption of Cd (II) was 146.2 mg/g. The biosorption kinetics of Cd (II) onto RMSB exhibit pseudo-first-order behaviour. The feasibility of the sorption process was established, and the thermodynamic parameters were determined. The Cd (II) sorption onto RMSB biomass has been estimated through the use of artificial neural networks (ANNs). With the high cross-correlation coefficient (R) value, the ANN models predicted the Cd (II) adsorption onto RMSB with remarkable accuracy. The outcomes showed that Cd (II) may be effectively removed from the aqueous solution using RMSB.
