Assess the performance of chemical coagulation process for microplastics removal from stormwater

Cost-Effective FeIVO2+ Generation for Antibiotics Removal in Electrochlorination of Mariculture Wastewater

“…For AS, there was no significant difference in the coagulation efficiency as the AS dosage varied from 0 to 1.0 mg/L. The primary mechanism of coagulation is usually divided into double-layer compression, adsorption, and sweep flocculation, according to related studies. , It was reported that the addition of PAM and AS strengthens the adsorption as well as sweep flocculation to varying degrees. , …”

As depicted in Figure 4c, all samples have intense peaks at 3336, 1510, 1356, and 964 cm −1 , which can be assigned to the OH stretch of H 2 O, −C�C, −C−C, and −C−O vibrations, respectively.…”

Generation and consequence of nano/microplastics from medical waste and household plastic during the COVID-19 pandemic

“…Biodegradation is influenced by various parameters, including polymer properties, organism type and pretreatment method. Molecular weight, crystallinity, tacticity, mobility, the variety of substituents and functional groups contained in the structure of a polymer, and the additives or plasticizers inserted into the polymer could take part in its decomposition ( Artham and Doble, 2008 ; Monira et al, 2021b ).…”

“…Polyvinyl alcohol (PVA), polyester (PEs), and polyvinyl chloride (PVC) are high-density polymers that are prone to sink and settle in the aquatic environment. Less dense polymers, such as PE, PS and PP, float in seawater because of their density ( Monira et al, 2021b ). However, different businesses or brands are responsible for the materials used to produce certain PPE.…”
