Abstract

The current study chemically recycled polystyrene waste using several methods. Specifically, sulfonated polystyrene PSS-01 was synthesized using the first method, and PSS-02 was synthesized using the second approach. FTIR, UV–visible, XRD, XRF, SEM, and TGA resulted in copolymers with high sulfonation degree, good thermal stability, and smooth and porous surfaces. The ability of the synthesized copolymers to remove turbidity from kaolin suspension was investigated. The highest turbidity removal or faster sedimentation was observed using PSS as a flocculant. The developed flocculant PSS-01 was more effective in the presence of kaolin than PSS-02. At best, by applying 300 mg/L of the solution, the highest turbidity removals of 92 and 78% were obtained by using 4 ppm PSS-01 at pH 6 and 8 ppm PSS-02 at the same pH, respectively. The removal difference was due to the composition and the degree of sulfonation between them. FTIR and XRD analysis proved the presence of the flocculant in the floc structure.

回收聚苯乙烯塑料废物：通过混凝-絮凝法去除浊度的可持续解决方案

目前研究用几种方法化学回收聚苯乙烯废料。具体而言，采用第一种方法合成了磺化聚苯乙烯PSS-01，采用第二种方法合成了PSS-02。FTIR、uv -可见、XRD、XRF、SEM、TGA等测试结果表明，共聚物磺化程度高，热稳定性好，表面光滑多孔。研究了合成的共聚物对高岭土悬浮液浊度的去除能力。使用PSS作为絮凝剂，观察到最高的浊度去除或更快的沉降。研制的絮凝剂PSS-01在高岭土存在下的絮凝效果优于PSS-02。在最好的情况下，使用300 mg/L的溶液，在pH为6时使用4 ppm的PSS-01和在相同pH下使用8 ppm的PSS-02，分别获得了92%和78%的最高浊度去除。去除率的差异是由它们的组成和磺化程度造成的。FTIR和XRD分析证实絮凝剂存在于絮体结构中。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
