In the present research, potential of two biochars produced by thermal decomposition wheat straw (BCS) and wicker (BCW) for Cr(VI) ions removing from wastewater was investigated. The pH presence chlorides nitrates were also Freundlich Langmuir models applied characterization adsorption isotherms. model has better fitting isotherms than model. sorption process can be described pseudo second-order equation. optimal capacities obtained at 2 24.6 23.6 mg/g BCS BCW, respectively. X-ray...
The goal of the study was to evaluate application biochar (BC) sewage sludge (SL) on adsorption and desorption capacity Cd(II), Cu(II), Ni(II) Zn(II). effect contribution in (2.5, 5 10%) investigated. isotherms data were fitted Langmiur (LM), Freundlich (FM) Temkin (TM) models. best fitting for kinetic obtained pseudo-second-order equation. experimental observed LM case SL BC, FM SL- SL/BC-amended soil. characterized by even four-order higher sorption than BC. addition BC next soil increased...
The purpose of this study was to develop an efficient method biochar modification for effective removal Se(VI) ions from water. Commercially available produced wheat straw impregnated by Fe(NO3)3 (0.8, 4 and 10% w/v) pyrolyzed at 200 °C. Optimum pH, adsorption kinetics, isotherms were determined the studied biochars. significantly increased biochar's ability adsorption. modified with has highest effectiveness. experimentally maximum capacity 14.3 mg g−1 pH 5, which optimum value. X-Ray...
Two groups of amine-functionalized organosilicas have been synthesized: amorphous polysiloxane xerogels (APX) and ordered mesoporous (OMO) by co-condensation tetraethoxysilane appropriate alkoxysilanes: aminopropyltriethoxysilane N-[3-(trimethoxysilyl)propyl]ethylenediamine. The obtained materials were characterized sorption measurements, X-ray diffractometry, elemental analysis, transmission electron microscopy, scanning microscopy. OMO samples well developed porous structure—the values...
Auranofin, a Food and Drug Administration-approved anti-rheumatic agent with anticancer properties for lung ovarian cancer, has never been studied pancreatic cancer. We hypothesize that auranofin may prevent ductal adenocarcinoma progression by inhibition of Txnrd1 HIF-1α.In vitro sensitivity human cell lines was determined based on IC50. Western blot assays were used to interrogate mechanisms apoptosis resistance. Ex vivo live tissue slice xenografts allowed testing larger number PDX...
Ordered mesoporous carbon (CMK-3), obtained from an abundant natural source, sugar, was thermochemically modified with dicyandiamide and thiourea as well by classical oxidization hydrogen peroxide to introduce specific surface groups. Thermochemical modifications resulted in almost unchanged porosity altered chemistry while of H2O2-treated seriously deteriorated. The carbons were tested sorbents diclofenac, considered one the emerging water contaminants. Changes significant differences...
