“…The increase in adsorption capacity with increase temperatures might result from increase in kinetic energy of the molecules such that it will effectively diffuse within the pore spaces of adsorbents and their collision will favor π-π overlapping between aromatic rings of DMP and biochar's. In addition, the positive change in entropy also indicates DMP affinity for the adsorbent and increase in stochasticity at adsorption interface during DMP uptake, similar trend was reported by and Ganie et al, (2021). The outcomes of thermodynamic study are tabulated in Table 6.…”

Rise in polymer industry and extensive use of their products leads to leaching of phthalate esters and distributed into the different matrices of the environment. These chemical group has the potential to hamper the life of living organisms and ecosystem. Thus, it is essential to develop cost effective adsorbents capable of removing these harmful compounds from the environment. In this work, peanut hull derived biochar was taken as the adsorbent, and DMP was selected as the model pollutant or adsorbates. The biochar’s of different properties were produced at three pyrolysis temperature (i.e., 450,550, and 650°C) to check how temperature affected the adsorbent properties and adsorption performance. Consequently, performance of biochar’s for DMP adsorption were thoroughly studied by the combination of experiments and compared with commercial activated carbon (CAC). All the adsorbents are meticulously characterized using various analytical techniques and used for adsorption DMP from aqueous solutions. The results suggested that adsorption was favoring chemisorption with multi-layered adsorption as adsorption kinetics and isotherm are in good alignment with pseudo second order kinetics and Freundlich isotherm, respectively. Further, thermodynamic study revealed DMP adsorption on adsorbent is physically spontaneous and endothermic. The removal efficiency order of four adsorbent was as follows: BC650 > CAC > BC550 > BC450 with maximum efficiency of 98.8% for BC650 followed by 98.6% for CAC at optimum conditions. And, as it’s a short carbon chain PAE, dominant mechanisms of adsorption for DMP onto porous biochar were H-bonding, π-π EDA interactions, and diffusion within the pore spaces. Therefore, this study can provide strategies for the synthesis of biochar for effectively removing DMP from aqueous solution.

“…Biochar‐based remediation exhibited lower efficiencies (<39% and <24%) at lower pyrolytic temperatures (550°C and 350°C, respectively) with the same feedstock material (Ganie et al, 2021). Distinct feedstock materials utilized for biochar preparation provided distinctive results, with removal efficiencies of 94.81%–100% (Wang, Sedighi, & Lea‐Langton, 2020; Wang, Sun, et al, 2021).…”

This review describes the occurrence and distribution of microplastics in freshwater and marine environments in recent years (2017–2022). Use of microplastics often results in contamination of aquatic environments, threatens biodiversity, and creates the need for environmental remediation. Such remediation strategies can involve primary, secondary, and tertiary treatments. Tertiary treatment is a frequent research subject due to its high efficiency and the possibility for advancements and enhancements. This study discusses tertiary treatments with remediation efficiencies of 95% and greater and their advantages, disadvantages, and future perspectives. Biochar‐mediated remediation of microplastics is an effective method that may be able to achieve efficiencies approaching 100%. The study concludes by exploring methods of removing microplastics, including constructed wetlands and biochar, which offer high efficiency. Practitioner Points Tertiary treatments are an effective microplastic remediation strategy applicable succeeding secondary or primary treatments or as an individual remediation strategy. Biochar is a highly efficient adsorbent for microplastic remediation from aquatic environment with eco‐friendly aspect and reusability. Modifications in tertiary treatments and enhancement in remediation efficiency are still a subject of research for future studies.

The presence of plastic waste in large quantities in the environment is a major problem and therefore a challenge for many researchers to examine the most effective methods of their disposal. In this paper, the source of microplastic and its hazardous effect on human health and interactions of plastics with plants were studied. Due to the specific physical-chemical features of micro- and nano-plastics, they are ideal candidates for the adsorption of organic pollutants, pathogens and heavy metals. The uptake and accumulation of nanoplastics by plants, adsorption studies, and bioaccumulation are shown here. In addition, recent research on the interaction of polystyrene micro- and nanoplastics with plants has been discussed. Many studies have shown that the most affected part of the plant was the roots, followed by leaves, shoots, and then the stem. Nanoplastics are found to be more harmful than microplastics due to permeation through the biological membranes of plants, while microplastics adhere to leaves.
