In this study, the photocatalytic degradation of methyl orange and Congo red dye was investigated inaqueous solution using C,N,S-tridoped SnO2 nanoparticles as a nano photocatalyst. The degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand pH of the solution. The results indicated that the degradation of methyl orange and Congo redwas...

A method for rapid and accurate determination of trace quantities of SbIII was developed based on its inhibitory effect on the decolorizing reaction of methyl orange in the presence of bromate and bromide ions in acidic media. Decolorization of methyl orange by the reaction products was used to monitor the reaction spectrophotometrically at 525 nm. The method allows determination of antimony in...

In the present study we show that recombinant bacterial CotA-laccase from Bacillus subtilis is able to decolourise, at alkaline pH and in the absence of redox mediators, a variety of structurally different synthetic dyes. The enzymatic biotransformation of the azo dye Sudan Orange G (SOG) was addressed in more detail following a multidisciplinary approach. Biotransformation proceeds in a broad ...

This study sought to investigate the effect of infusions from green tea (Camellia sinensis) and some citrus peels [shaddock (Citrus maxima), grapefruit (Citrus paradisi), and orange (Citrus sinensis)] on key enzymes relevant to the management of neurodegenerative conditions [monoamine oxidase (MAO) and butyrylcholinesterase (BChE)]. The total phenol contents and antioxidant activities as typifi...

A study on binding of antitumor chelerythrine to human telomeric DNA/RNA G-quadruplexes was performed by using DNA polymerase stop assay, UV-melting, ESI-TOF-MS, UV-Vis absorption spectrophotometry and fluorescent triazole orange displacement assay. Chelerythrine selectively binds to and stabilizes the K(+)-form hybrid-type human telomeric DNA G-quadruplex of biological significance, compared w...

The chemical composition of sweet potato (Ipomoea batatas var. Portu Orange), grown in Ukraine, was studied to determine its potential shortbread technology. Orange has a high content starch (11.2 %), natural sugars (4.7 dietary fiber (3.8 %) and food pigments. To obtain the highest quality characteristics preserve antioxidant properties during drying, an innovative microwave vacuum drying meth...

Background and purpose: Generated dye wastewater by the textile industry is usually toxic, non-biodegradable and resistant in the environment. Eggshell is one of the inexpensive material and for the reason the vesicular structures can be used as a proper adsorbent for pollutants removal. The aim of this study is to investigate the efficiency of eggshell for removal of acid orange 2 dye from aqu...

BACKGROUND The constituents in a food emulsion interact with each other, either physically or chemically, determining the overall physico-chemical and organoleptic properties of the final product. Thus, the main objective of present study was to investigate the effect of emulsion components on beverage emulsion properties. RESULTS In most cases, the second-order polynomial regression models w...
