Competitive adsorption of diethyl phthalate (DEP), dibutyl
The adsorption capabilities of biochars and BG composites towards dimethyl phthalate (DMP), diethyl phthalate (DEP), and dibutyl phthalate (DBP) as model phthalic acid esters (PAEs) were examined
Adsorption and removal of phthalic acid and diethyl phthalate
The adsorption of diethyl phthalate (DEP) was also investigated with the various MOFs and AC adsorbents ( Fig. 6 ). As shown in Fig. 6 a, the adsorption capacity of DEP with ZIF-8 or UiO-66s was not as promising as observed in the adsorption of H 2 -PA.

to biochar can have an impact on their behavior. So far, the competitive adsorption of phthalates on biochar has not been reported. In this study, biochar from corn cobs was produced and characterized for the competitive adsorption of diethyl phthalate (DEP), dibutyl phthalate (DBP) and di (2-ethylhexyl) phthalate (DEHP).
Adsorption of diethyl phthalate ester to clay minerals
Phthalate esters are a group of plasticizers, which have been widely detected in China’s agricultural and industrial soils. In this study, batch adsorption experiments were conducted to investigate the environmental effects on the adsorption of diethyl phthalate ester (DEP) to clay minerals.
Genotoxic activity of endocrine disrupting compounds commonly
In the present study we evaluated cytotoxic and genotoxic activities of endocrine disrupting compounds (EDCs), including dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), di (2-ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and nonylphenol (NP), which have been previously identified in
- Does dibutyl phthalate (DBP) adsorption work on corncob biochar (fresh and oxidized?
- So far, the competitive adsorption of PAEs to biochar has not been reported. In this study, the competitive adsorption of Dibutyl phthalate (DBP) and Di (2-ethylhexyl) phthalate (DEHP) on corncob biochar (fresh and oxidized) was investigated, and experiments of kinetics, isotherms, and thermodynamics were conducted.
- What are the adsorption kinetics of DBP and DEHP?
- Adsorption kinetics of DBP and DEHP under mono (a, c) and binary (b, d) conditions. To further understand DBP and DEHP’s adsorption actions, the adsorption kinetics were analyzed using the pseudo-first-order model and the pseudo-second-order model. All models and the parameters were presented in Supplementary Material S3.
- Does DEHP inhibit DBP adsorption?
- Apparently, in a binary PAEs system with high PAEs concentration, the accessible adsorption sites on biochar were preferentially occupied by DEHP, contributing to DBP adsorption inhibition. In contrast, the adsorption of DEHP was only marginally inhibited.
- Which phthalate has a bioaccumulation potential?
- For example, some of the PAEs, e.g., Dibutyl phthalate (DBP); Di (2-Ethylhexyl) phthalate (DEHP); Butyl Benzyl phthalate (BBP) and Diethyl phthalate (DEP), have bioaccumulation potentials and are considered endocrine-disrupting chemicals and classified by many countries as "priority pollutants" (Lu et al., 2009).
- Are DBP & DEHP adsorbable in environmental samples?
- DBP and DEHP are the most frequently reported PAEs in environmental samples (Peijnenburg and Struijs, 2006). Because of their prevalence in the environment, it is meaningful to compare DBP and DEHP’s adsorption behavior.
- Why is DBP more adsorbable than DEHP?
- The higher hydrophobicity of DEHP could explain the stronger adsorption of DEHP than DBP. In contrast, DBP’s faster adsorption could be attributed to its smaller size and shorter chains, therefore faster diffusion.
