Effect of dibutyl phthalate as plasticizer on high-molecular
dibutyl phthalate (DBP) as plasticizer were prepared by solution casting method. The interaction between the PVC, Li 2B 4O 7, and DBP were studied by Fourier transform infrared. The shifting, broadening, and splitting of trans-mission peaks were the evidences of complexation. The highest ionic conductivity polymer electrolyte of 2.83×
Effect of dibutyl phthalate as plasticizer on high-molecular
High mass fraction of DBP would weaken the interactions within the polymer chains and reduces the solvation of Li cations by polymer matrix. It initializes the decoupling of ions, enhances the dynamic free volume of the polymer system and thereby increases the ionic conductivity.
Effect of dibutyl phthalate as plasticizer on high-molecular
The use of a large amount of toxic synthetic materials leads to an increase in the pollution of environmental objects. Phthalates are compounds structurally related to esters of phthalic acid that
Phthalate Exposure and Children’s Health - PMC
High molecular weight (HMW) phthalates including di-2-ethylhexyl phthalate (DEHP), butyl benzyl phthalate (BBzP), di-n-octyl phthalate (DnOP), di-isononyl phthalate (DiNP), and di-isodecyl phthalate (DiDP) are commonly used as plasticizers to impart flexibility in hard polyvinyl chloride plastics (Table 1). HMW phthalates are also used in
Risk Management for Phthalates | US EPA
Phthalates are used in many industrial and consumer products, many of which pose potentially high exposure. Phthalates have been detected in food and also measured in humans. Adverse effects on the development of the reproductive system in male laboratory animals are the most sensitive health outcomes from phthalate exposure.
- How do plastic properties affect dibutyl phthalate release?
- It was found that plastic properties, such as particle size, plasticizer content and aging of plastics had a great effect on the leaching of dibutyl phthalate (DnBP). Phthalate release was generally higher in smaller particles and particles with higher phthalate content.
- Does dibutyl phthalate release toxic chemicals and risks associated with microplastics?
- In this study, the release of dibutyl phthalate (di-n -butyl phthalate, DnBP), a commonly used phthalate plasticizer, was targeted. The findings of this study would provide valuable information for evaluation of toxic chemicals and risks associated with microplastics. 2. Materials and methods 2.1. Microplastics
- What is dibutyl phthalate (DPB)?
- Dibutyl phthalate (DPB) belongs to the common phthalic acid esters (PAEs) and is used extensively as a plasticizer during the polymerization process (Tao et al., 2022).
- Do phthalate plasticizers affect DNBP release?
- Collectively, the results demonstrated that the presence of another phthalate plasticizer in plastics did not compromise the beneficial effect of fulvic acid on DnBP release, and the increase of pollutant solubility played a more significant role in the enhanced DnBP release than the increased affinity of leaching solution for microplastics.
- How do microplastics affect phthalate release?
- More phthalate was released from microplastics with higher phthalate content. Natural aging of plastics led to changed phthalate release. Coexistence of fulvic acid and NaCl had a greater effect on phthalate release than fulvic acid alone. Leaching of surface-active DOC from plastics could promote the release of phthalate plasticizer.
- Are phthalate plasticizers harmful?
- Phthalate plasticizers are endocrine disruptors, and could cause adverse developmental and reproductive effects in humans and animals (Mankidy et al., 2013; Sedha et al., 2021). Therefore, their release into the environment may endanger the health of biota, which merits urgent research.
