“…The homogenized microplastic samples were taken from each flask, and then used to measure the characteristics of the microplastic particles (Lwanga et al 2018). The Brunauer‐Emmett‐Teller specific surface area and pore size distributions of microplastic particles were measured using the nitrogen adsorption technique with an ASAP 2020 surface area and porosity analyzer (Micromeritics; Zhang and Leiviskä 2020). Characteristic functional groups of microplastic particles were analyzed through a Bruker Vertex V80 vacuum Fourier transform infrared spectrometer (Perkin‐Elmer FTIR 2000) in the 4000 to 400 cm −1 wavenumber region (He et al 2020).…”

Microplastic pollution has become an increasingly pervasive issue worldwide, but little is known about its effects on the soil environment. A soil microcosm experiment was conducted using low‐density polyethylene microplastics to estimate the effect of microplastic pollution on soil nutrient cycling and the soil microbial community structure. The results showed that microplastic addition significantly promoted soil carbon dioxide emissions but not soil nitrous oxide emissions. Soil pH, dissolved organic carbon, ammonia nitrogen, the contents of total phospholipid fatty acid (PLFA), and the ratios of gram‐positive bacteria to gram‐negative bacteria and saturated to monounsaturated PLFAs significantly increased. In addition, nitrate nitrogen and the ratios of fungi to bacteria, total iso‐branched fatty acids to total anteiso‐branched fatty acids, and cyclopropyl to precursor significantly decreased with increasing microplastic addition. The addition of microplastics decreased the abundance of ammonia oxidizing bacteria and nitrite reductase (nirS) but had little effect on the functional genes of ammonia oxidizing archaea, nitrite reductase (nirK), and nitrous oxide reductase. A principal coordinate analysis of the bacterial 16S ribosomal RNA gene and fungal internal transcribed spacer in the microplastic addition treatments revealed that the bacterial and fungal communities formed an obvious cluster. The average abundance of some microbial species with tolerance and degradability to microplastics, such as Nocardioidaceae, Amycolatopsis, Aeromicrobium, Cytophagaceae, Betaproteobacteria, Rhodoplanes, and Mortierella, in the microplastic addition treatments was significantly higher than that of the control treatment. The results suggested that microplastics have obvious influences on microbial communities and may affect global carbon and nitrogen cycles. Environ Toxicol Chem 2021;40:352–365. © 2020 SETAC

“…In this case, characteristics change on sorbent surface due to graphene combination must have been a critical function. Furthermore, other report informed that quaternary ammonium-modified pine bark could be employed as sorbent for adsorbing vanadium [56]. They revealed that the initial sodium hydroxide concentration as a determining factor.…”

In this review article, the recent development of organic sorbents derived from plant and animal waste for treating polluted aqueous media is presented. The application of biomass has been recognized reliable to adsorb hazardous pollutants contained in wastewater generated by emerging industries. This paper also discusses other existing technologies for removing pollutants including heavy metals, dyes, oil and grease, antibiotic and phenolic compounds from polluted aqueous media. Furthermore, several prominent examples of plant and animal wastes such as eucalyptus bark, pine bark, rice husk, various fruit peels, and animal bones are also properly reviewed. The effects of modification techniques on sorbent performance such as carbonization, pyrolysis, and chemical impregnation using acid or alkaline chemicals are considerably included. Some gaps in current literature are also discussed including the tendency of certain targeted pollutants, the use of simulated aqueous media, the scale of research projects, and the prominent modification procedures. Eventually, based on the relevant literature, clear conclusion has been drawn that these natural disposals have great potentiality as environmentally friendly sorbent alternative to other commercial expensive sorbents, and their reuse has been part of green solutions supporting a circular economy system.

“…Due to the lack of binding sites after adsorption saturation, the removal rate decreases with the increase of initial concentration 34 ; 3. The Brownian motion of the adsorbent increases with the increase of temperature, which is conducive to adsorption 35 ; 4. The degree of carboxyl hydrolysis is enhanced, the adsorption sites are activated, and the adsorption capacity increases; 5.…”

Waste white foam, toxic dyes, and metal ions are difficult to degrade in the ecological environment, posing a serious threat to human health and natural beauty, it is of great significance to design a functional material to jointly solve these problems. This study provided a facile approach to convert waste polystyrene foam into a new acid anhydride modified polystyrene adsorbent (PS-MA) for the dyes and heavy metals removal from aqueous solution. The as-obtained absorbent was characterized by Fourier transform infrared spectroscopy, thermogravimetry, scanning electron microscopy, energy dispersive spectroscopy, Brunauer Emmett Teller method, and X-ray photoelectron spectroscopy. Influencing factors are including, pH, dye concentration, contact time and temperature on the adsorption of methylene blue (MB), safranine T (ST), and Cu(II) were systematically studied. Boehm titration showed that the content of surface carboxyl groups reached 4.53 mmol/g. The maximum adsorption capacity had reached 1405.37 mg/g for MB, 2269.33 mg/g for ST, 65.03 mg/g for Cu(II). Moreover, the kinetic data were in good agreement with the pseudo-second-order model and closed to adsorption equilibrium at 20 min. After five times of recycling experiments and the application of mixed dye wastewater with salinity, PS-MA showed excellent stability and removal ability. Abundant efforts revealed a broad application prospect of PS-MA materials in water remediation.
