Hydrogels have attracted great attention as good adsorbents due to their extraordinary water retention capacity, unique hydrophilic nature, biocompatibility, and abundance in availability. In this work, a superabsorbent polymer (SAP) hydrogel its composite were synthesized, with the introduction of activated charcoal (SAP-AC) for deep removal ecotoxic organic dye methylene blue (MB). The format...

The aim of this work is to investigate the enhancement UVC-based tertiary treatments; for purpose, real wastewater treatment plant (WWTP) effluent was spiked with a model pollutant, namely acetaminophen. UVC irradiation resulted in some photodegradation acetaminophen, which enhanced upon addition hydrogen peroxide (11 mM), but higher amounts oxidizing agent no significant acceleration process. ...

This study aiming to determine the optimal conditions degrade an organophosphate pesticide diazinon (DZN) at low levels concentrations (μg.mL−1) and identify by-products generated. The degradation processes utilized were Fenton photo-Fenton. iron concentration [Fe2+], hydrogen peroxide [H2O2], solution pH are investigated parameters. Doehlert three-parameter experimental design was applied mode...

Seeds of plants from Ipomoea genera contain numerous ergot alkaloids, including psychoactive ergine and ergometrine, and are often abused as so-called "legal highs." In this work, an analytical method for determination of ergine and ergometrine, and identification of other alkaloids was developed, optimized, and validated. Three extraction techniques, ultrasound-assisted extraction in bath, or ...

A successful photodynamic therapy (PDT) requires a specific photosensitizer, oxygen and light of a specific wavelength and power. Today photodynamic therapy (PDT) is administered to patients with light-emitting diode (LED) panels. These panels deliver a non-uniform light distribution on the human body parts, as the complex human anatomy is not a flat surface (head vertex, hand, shoulder, etc.)....

A previous study showed that filamentous phage could be efficiently transfected into mammalian cells in the presence of the cationic lipid Transfectam. In the present study, we used an experimental plan based on a uniform network (Doehlert) matrix to estimate optimal transfection conditions in two different cell lines, CHO and Cos-7. Using the cationic lipid RPR120535b as a model, we show that ...

Untreated Pinus radiata sawdust was investigated for the removal of Cu+2 ions from aqueous solutions. The biomass characterized by Inductively Coupled Plasma-Mass (ICP-MS) spectrometry and Scanning Electron Microscopy with an Energy Dispersive X-ray spectroscopy (SEM-EDX), X-Ray crystalline powder Diffraction (XRD) Fourier Transform Infrared (FTIR) spectroscopy, before after adsorption. influen...

Wheat alpha-amylase/trypsin inhibitors remain a subject of interest considering the latest findings showing their implication in wheat-related non-celiac sensitivity (NCWS). Understanding functions such disorder is still unclear and for further study, need pure ATI molecules one limiting problems. In this work, simplified approach based on successive fractionation extracts by reverse phase ion ...
