“…of biosorption at solution pH 4.0 and 25.0 °C. Orange peel waste with silica nanospheres (SiO2@OPW) was modified by Saini et al, [68] and applied for capturing Pb(II) from wastewater. An excellent biosorption rate was achieved at optimum conditions as 200 mg/g by hybrid biosorbent, while pure OPW showed 166.7 mg/g biosorption capacity for the extraction of studied metal ions.…”

Wastewater containing heavy metals (HMs) beyond permissible limit has to be decontaminated by an appropriate treatment method. Numerous conventional methods have been applied for heavy metal decontamination including chemical precipitation, ion exchange, electrolysis and membrane applications, etc. Most conventional methods are less efficient for the decontamination of metals due to the resistance and persistence of HMs in wastewater. Even so, the conventional methods have their limitations; adsorption using low-cost hybrid bioadsorbents has been explored as an environmentally friendly method for the removal of metal ions from wastewater. This review has been summarized the sources and effects of different heavy metals in the water/wastewater. The possible treatment methods also highlighted their advantages and limitations. Factors affecting the biosorption process such as bioadsorbent dosage, solution pH, contact time, initial concentration, temperature, and ionic potentials attracting to metal ions have been evaluated by the published researches. Moreover, the possible mechanisms of metal biosorption were discussed in light of previous studies. According to this review, hybrid bioadsorbents are outstanding materials due to their exciting physicochemical properties and other characteristics including eco-friendly nature, low cost, nontoxic, high adsorption capacity, and reusability. This review could be considered as a precious pathway for exploring more low-cost, environmentally friendly hybrid adsorbents for metal decontamination from wastewater, eventually, the review will contribute to environmental remediation and purification applications of biomaterials.

“…Biogenic silica from bamboo leaves was also successfully synthesized using the sol-gel method application of photocatalytic composites for degradation of methylene blue with a very good semiconductor energy bandgap [30]. Several other plants such as sugar palm peel, pineapple leaf, and orange peel are useful as the main raw material in the manufacture of silica material which has the potential for adsorption, photocatalysis, degradation, and [31], [32]. One study also reported that one of Indonesia's natural resources, namely, rice husks has the potential to synthesize SiO2 with a high purity level of 99.258% with coprecipitation techniques [33].…”

The existence of water on earth is very abundant and has a vital role in the source of life for every living creature. In managing water resources, pollution is one of the issues world researchers face. This article reviews the characteristics and methods of synthesizing Fe2O3 and SiO2 materials to prevent water pollution. The strategies administrated antecedently square measure vapor deposition, microemulsion, solvothermal, coprecipitation, sol-gel, and hydrothermal. The formation of fine quality nanoparticles with controlled size associate degreed size distribution square measure typically achieved by selecting an applicable solvent mixture and varied parameters like temperature, pressure, and time interval.
