Green chemistry methods for production of nanoparticles have many advantages, such as ease of use, which makes the methods desirable and economically viable. The aim of the present work was to green synthesise silver nanoparticles (SNPs) using aqueous tangerine peel extract in different ratios (2:1, 1:1, 1:2). The formed SNPs were characterised using ultraviolet-visible (UV-Vis) spectrophotomet...

In the previous chapter, the focus was mainly on the behavior of ions in solution. The effect of concentration, solvent, as well as pH have been investigated; furthermore, alkali metal ions as well as transition metal ions have been studied. In this chapter, the investigation will be extended from ions to molecules, more specifically toward the behavior of amino acids in solution. Amino acids a...

The diffusion of sugar in aqueous solution is important both in nature and in technological applications, yet measurements of diffusion coefficients at low water content are scarce. We report directly measured sucrose diffusion coefficients in aqueous solution. Our technique utilises a Raman isotope tracer method to monitor the diffusion of non-deuterated and deuterated sucrose across a boundar...

The interaction between felodipine and bovine serum protein was studied, the optimal experimental conditions were selected, fluorescence quenching mechanism discussed. filodipine determined by UV spectrophotometry, selected control variable method. of in system explored spectrophotometry. intensity most obvious under buffer solution pH 7.4, concentration 8.0*10 -4 mol/L, reaction time 30min 25°...

industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...

Abstract The article presents the results of studying degree destruction phycocyanin in composition protein module under various pasteurization modes. objects study were: dry sodium caseinate with a mass fraction 85%, whey concentrate 80% matter, extract containing 42.7 wt.% phycocyanins. 1% aqueous solutions were prepared from each object. Sorption by matrix was carried out combining an soluti...

In this study, we investigated the degradation of amido black dye in an aqueous solution using ultra-violet (UV) light catalyzed by iron oxide nanoparticles (nano-Fe). The nano-Fe was synthesized sodium borohydride reduction ferric chloride and characterized scanning electron microscopy (SEM), X-ray diffraction (XRD), fluorescence spectrophotometry (XRF). SEM showed regular spherical particles,...
