“…Besides the industrialized zone, landfill dumping sites have been the sink for PAEs, as documented in the literature works [86,78]. Consequently, landfill leachates have been contaminating the nearby water sources [92,93,94]. Lee et al The occurrence of PAEs is not only found in wastewater samples and tap water but is also in bottled water [87,76].…”

In this era of globalization, plastic is regarded as one of the most versatile innovations, finding its uses ranging from packaging, automotive, agriculture, and construction to the medical and pharmaceutical industries. Unfortunately, the single-use nature of plastics leads to ecological and environmental problems. Among conventional disposal management of plastic waste are landfilling dumping, incineration, and recycling. However, not all plastic waste goes into disposal management and ends up accumulating in lakes, rivers, and seas. In the aquatic environment, the action of photochemical weathering plastics has resulted in the release of chemical additives such as phthalic acid esters (PAEs), an important plasticizer added to plastic products to improve their softness, flexibility, and durability. Nowadays, PAEs have been ubiquitously detected in our environment and numerous organisms are exposed to PAEs to some extent. As PAEs carry endocrine disruptive and carcinogenicity properties, an urgent search for the development of an efficient and effective method to remove PAEs from the environment is needed. As a viable option, titania (TiO2) photocatalysis is a promising tool to combat the PAEs contamination in our environment owing to its high photocatalytic activity, cost-effectiveness, and its ability to totally mineralize PAEs into carbon dioxide and water. Hence, this paper aims to highlight the concerning issue of the contamination of PAEs in our aquatic environments and the summary of the removal of PAEs by TiO2 photocatalysis. This review concerning the significance of knowledge on environmental PAEs would hopefully spark huge interest and future development to tackle this plastic-associated pollutant.

“…This is because, at slightly alkali conditions, ionization of -COOH can occur and produce -COO-group and -OH group. As a result, the -OH group will increase thus, causing intramolecular electrostatic repulsion which will enhance the uncoiling and extension of the polymeric chain (Lürling et al 2020;Aziz et al 2021). This will result in more adsorption sites available and a more complex structure can be formed for the removal of pollutants.…”

The coagulation process has become a common treatment method in water and wastewater treatment but not in palm oil mill effluent (POME) treatment. POME is known to have a high level of COD and turbidity and prior studies showed that the modified coagulation process using bio-coagulant may be feasible to remove primarily the COD and turbidity of the POME. In this study, an extract of Saccharum officinarum or bagasse is used as a source of bio-coagulant for the removal of COD and turbidity from POME at optimized coagulant dosage, pH, and contact time. The optimization was carried out via response surface analysis. This analysis stipulated that the application of Saccharum officinarum extract removed turbidity of more than 95%, COD of more than 65.0% with coagulation activity of 67.4% at optimum 50 mg/L coagulant dosage, pH 8, and slow mixing for 30 minutes. Henceforth, this study concludes the suitability of Saccharum officinarum as a bio-coagulant to primarily remove organic and solid pollutants during POME pre-treatment.
