the thesis tests for 6 types of pes (dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DIBP), dibutyl phthalate (DBP), butylbenzyl phthalate (bbp) and di(2-ethylhexyl) phthalate (dehp) in widely used bottled water brands produced in the uae. 126 bottled water samples were extracted by liquid-liquid extraction using
the leaching of phthalates from pvc can be determined with an,nov 6, 2019 · spiking and leaching experiments using bis(2-ethylhexyl) phthalate as a model phthalate enabled the validation and evaluation of the designed infinite sink method. the developed method offers: a low-cost and simple approach to investigate leaching of phthalates from pvc into aqueous environments
- How many phthalate esters are there in Chaohu sewage treatment plants?
- The concentrations, and removal rates of five phthalate esters (PAEs) (dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), diisobutyl phthalate (DiBP) and di (2-ethylhexyl) phthalate (DEHP)) in the five representative sewage treatment plants of Chaohu catchment were investigated by season in this study.
- What are the limits of detection for phthalates?
- The limits of detection for (DEP, DAP, BBP, DBP, DCHP, DHP, DEHP, DOP, DINP, and DIDP) were 0.02, 0.04, 0.01, 0.03, 0.02, 0.03, 0.03, 0.01, 0.08, and 0.10 mg L, respectively. HPLC-PAD; PVC toys; phthalates; ultrasonic extraction.
- Are phthalic acid esters leaching kinetics and governing mass transfer?
- Phthalic acid esters (phthalates) have been detected everywhere in the environment, but data on leaching kinetics and the governing mass transfer process into aqueous systems remain largely unknown.
- Is abld the governing diffusion process for the continuous leaching of phthalates?
- We show that ABLD is the governing diffusion process for the continuous leaching of phthalates because phthalates are very hydrophobic (partitioning coefficients between PVC and water log KPVC/W were higher than 8.6), slowing down the diffusion through the ABL.
- Does bis-2ethylhexyl phthalate affect fish Pearl spot?
- Effect of Bis-2ethylhexyl phthalate (DEHP) on commercially important tropical fish pearl spot has not been demonstrated at environmental concentrations along with depuration. The species is estuarine, juvenile and difficult to maintain but widely consumed and well distributed in tropical estuaries.
- How long does dpvc desorption last?
- Also, the diffusion coefficient in the polymer DPVC is relatively high (∼8 × 10-14 m2 s-1) and thus enhances IPD. Desorption half-lives of the studied PVC microplastics are greater than 500 years but can be strongly influenced by environmental factors.
