Comprehensive review on phytotechnology: Heavy metals removal by diverse aquatic plants species from wastewater

Biosorption of lead (II) from an aqueous solution using biosorbents prepared from water plants

“…Currently, chemical, physical, and biological methods are implicated for the removal and stabilization of metals (including Pb) in the environment. Commonly used methods for the treatment of metals are precipitation, electrochemical treatment, membrane technologies, lime coagulation, solvent extraction, membrane filtration, reverse osmosis, ion exchange, and adsorption [9]. Each process has its own merits and limitations in application, so these traditional metal removal methods have certain disadvantages.…”

“…Each process has its own merits and limitations in application, so these traditional metal removal methods have certain disadvantages. In some cases, these methods are too expensive, inefficient, and release toxic waste [9]. Thus, it is essential to develop alternative methods for the successful treatment of metals which are low-cost, efficient, and nature-friendly.…”

“…The growing international demand for proper adsorbents has led to a search for new, readily available, and low-cost materials [10]. In recent years, the adsorption of heavy metals on the surfaces of various natural biomasses, including dry plant leaves [11], rice husks [12,13], barks [14], waste tea leaves [15], and many other locally abundant biomaterials have been studied [9]. Because it is known that aquatic plants, both living and dead, are heavy metal accumulators, several recent studies have investigated the removal of heavy metals by using biomaterials prepared using dried plant species [16,17].…”

“…Subsequently, the application of biosorbent materials prepared from aquatic plants for the removal of heavy metals from wastewater has gained widespread interest in environmental remediation [18]. The selection of an optimal plant species for metal removal includes a variety of factors, such as the yield of biomass, the ease of growth of the plant, and the ease of harvest under the conditions of application [9]. It has been well-established that EC and its dried biosorbents, possesses a strong ability to remove heavy metals from aqueous solution, with the sorption performances vary depending on the metal species, concentration, and solution chemistry [16,19,20].…”

Ecological modelling of a wetland for phytoremediating Cu, Zn and Mn in a gold–copper mine site using Typha domingensis (Poales: Typhaceae) near Orange, NSW, Australia

“…Similarly, using a predictive-ecosystem simulation model, Mitsch and Wise (1998) designed a wetland that included Typha latifolia in which Fe contents dropped from 166 to 32 mg/L and that of Al dropped from 83 to 56 mg/L from the inflow to the outflow points.
