The removal mechanism and performance of tetrabromobisphenol A with a novel multi-group activated carbon from recycling long-root Eichhornia crassipes plants

Abstract

MGAC showed excellent adsorption performance for TBBPA and provide an ecologically friendly way to deal with eutrophic plants.

Targeting Proinflammatory Molecules Using Multifunctional MnO Nanoparticles to Inhibit Breast Cancer Recurrence and Metastasis

“…Three typical peaks (i.e., CO, C–O, and CC) of tannic acid were detected in FTIR spectra of the MnO nanoparticles (Figure S2), suggesting the presence of tannic acid molecules. In addition, the high-resolution C 1s XPS spectrum of MnO nanoparticles exhibited three peaks at 284.6, 286.5, and 288.7 eV, which are responsible for the C–C, C–O–C, and O–CO bonds of the tannic acid molecules, , respectively (Figure S3). The X-ray diffraction (XRD) pattern in Figure S4 revealed that the MnO nanoparticles presented a broad peak from 18 to 30° without any clear diffraction peaks, suggesting their amorphous structure.…”

Exploring of the sorption mechanism of endocrine disruptors on a newly developed cost-effective microporous material derived from puck (Afroxtyrax lepidophyllus) shell

“…This methodology makes it possible to independently evaluate the variable parameters of the experiment but also the influence of the interaction between these variables on the response. Within the framework of this study, four independent parameters were varied, these are: the pH of the solution (5)(6)(7)(8)(9)(10)(11); the mass of CRP Where Y is the predicted adsorption percentage, a0 the constant coefficient, ai the linear coefficients, aii the quadratic coefficients, aij the interaction coefficients and xi, xj are the coded values of the variables and ε the uncertainty between measured and predicted values.…”

“…Known as a flame retardant and widely used in several fields, this molecule finds its usefulness in textile products, plastics and also in electronics [4,5]. As a resistant pollutant, TBBPA is the most used flame retardant, it is insoluble in water which could be the main reason for its accumulation in the body and thereby interfering with the functioning of the endocrine system and inducing harmful effects on the body [6,7]. The TBBPA was produced at approximately 170000 t/an in 2004 [8] and has required in recent years several controls and restrictions for its use in the manufacture of materials in contact with water or food intended for human consumption [9].…”

“…There are many depollution techniques used to eliminate pollutants in aqueous solution such as degradation using photo-fenton or photocatalytic [10] process, precipitation, ultrafiltrationcomplexation [11], ion exchange membranes [12], coagulation-floculation [13]and adsorption which are done on adsorbents such as Clays, metal-organics framework and activated carbon [7,14]. Due to its easy implementation, relatively low cost and high efficiency, adsorption is the most popular technique in developing countries [15].…”

Nitrogen-Doped Carbon Nanoflakes by Acidic Charring of Microcrystalline Cellulose and Urea for the Rapid Removal of Imidacloprid from Water

“…43 The deconvoluted short scan of O 1s shows two peaks at ∼531.17 and ∼532.88 eV corresponding to C�O and C-O, respectively (Figure 2(d)). 44,45 The high- resolution short scan of N 1s shows two peaks at ∼399.73 and ∼400.72 eV corresponding to C-N-C and C-N, respectively (Figure 2(e)). 46 The deconvoluted short scan of S 2p shows three peaks at ∼163.04, ∼167.69, and ∼169.1 eV, corresponding to C-S, C-SO 2 , and C-SO 3 , respectively (Figure 2(f)).…”
