“…24,25 The electrochemical and ion exchange methods are high-cost and considered less efficient. 26 Consequently, adsorption is considered an alternative method in the removal and recovery of nutrients from wastewater. The adsorption process participates in the recovery of nutrients using environmentally benign adsorbent materials, so that the recovered nutrients can be reused.…”

“…They often possess atomic weights higher than iron and densities below 5 g/cm 3 , finding applications in various industries, including smelting, finishing, coal, electroplating, photography, aerospace, waste management, transportation, mining, and agriculture [11,12]. Essential metals like copper (Cu), nickel (Ni), chromium (Cr), mercury (Hg), cadmium (Cd), zinc (Zn), and lead (Pb) are prevalent in industrial processes, emphasizing their role in determining water quality [13,14]. When present in water, these pollutants can adversely affect human well-being, leading to developmental inhibition, male feminization, and waterborne diseases, impacting both developed and developing nations [7,15].…”

Environmental contamination by heavy metals poses significant threats to terrestrial and aquatic ecosystems, necessitating the development of effective remediation strategies. Conventional methods for heavy metal removal exhibit limitations, including inadequate efficiency and elevated costs. In this context, microalgae have emerged as a promising bioremediation approach due to their robust metal-binding capabilities, specifically through biosorption. This review comprehensively examines the role of microalgae in addressing heavy metal pollution, with a primary focus on their effective removal from wastewater. Microalgae offer wastewater purification potential across diverse sources and capitalize on wastewater as a growth matrix, yielding valuable bioproducts, biomaterials, and bioenergy. Their versatility allows them to thrive in various wastewaters, facilitating effective contaminant removal. This study also investigates the application of microalgae in decentralized water treatment systems (DWTSs), where the decentralized nature of these systems proves advantageous in addressing heavy metal contaminants directly at the point of generation or use. This approach holds particular significance in regions where centralized systems face obstacles due to geographical constraints, inadequate infrastructure, or financial limitations. DWTSs not only provide a decentralized solution for heavy metals removal but also prove advantageous in disaster relief scenarios and rapidly growing urban areas.

“…Therefore, even at a low concentration level, it is important to quantify and determine these destructive pollutants from various sources. In addition, sample pretreatment procedures need enhanced proficiency and selectivity because of the complicacy and diversity of the sample matrices (Aziz et al, 2020;khan et al, 2021a). It is imperative to design and construct some new adsorbents with high extraction efficiency, such as amberlite resins, silica gel, graphene oxide, chelating resin, carbon nanotubes, activated carbon, graphene and so on (Arabi et al, 2017;Bagheri et al, 2019;Ma et al, 2018;Azzouz et al, 2018).…”
