Fourier transform spectroscopy

and lactic acid concentrations on a regular basis (at the start of MLF and every seven days thereafter) until its completion (taken as the point when the malic acid concentration is equal to or lower than 0.3 gIL). This was done by Fourier-transform Infrared Spectroscopy (FT-IR) (WineScan FT120, FOSS Analytical, Denmark) as well as determination of the malic acid concentration with an enzymatic assay (Roche, Boehringer Mannheim,…

ABSTRACT Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous system.Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Poor watersolubledrugs often require high doses in order to reach therapeutic plasma concentrations after oral administration. Low aqueoussolubility is the major problem encountered with formulation development of new chemical entities. Any…

such as % volume fraction of coir extract, concentration of metal precursor, contact time and solution pH on the formation of AuNPs was evaluated to determine the optimum conditions for synthesis. As synthesized AuNPs were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray analysis…

Chapter: Soil, Water and Air Pollution 1. Introduction: Definitions of soil, water and air pollution; sources and types of soil, water and air pollution, soil and water pollution status in India With rapid increase and development in industrial and agricultural sectors along with population explosion, huge amount of organic and inorganic waste is released in environment and causing serious threats to environment and agro-ecosystem. This procedure can bring about a danger in the human wellbeing.…

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

Chapter 1 Introduction Waste generated from food industries is a source of an untapped energy which is mostly dumped inland fills whereby it releases greenhouse gases into the atmosphere. It is very difficult to treat and recycle food waste due to its composition. Food industry produces large volumes of wastes, both solids and liquid, resulting from the production, preparation and consumption of food. These wastes lead to increasing waste disposal and can pose severe pollution problems and…
