Calibration

Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…

Florentini Florentini Task 2 Interview INBA 3810 In this second assignment, I will discuss further and provide more details about the “international aspect of my uncle’s work. For example, what different approached did they use?. What risks did they face?. I would like to discuss more about the competition in the international palm oil market as well, and how to price right for different customers in different countries. In my interview with Karim, I learned a lot about what he does as a…

The solution was then made up to 100ml volume with pH 6.8 phosphate buffer and mixed thoroughly. The solution was filtered, diluted and drug content was estimated by UV spectrophotometer at 260nm.The drug concentration was calculated from the calibration curve…

Material and Method ================ The practical course of the present study was implemented in the farm ofFaculty of Agriculture,Minia University, Minia Governorate. 2.1. Animals: The present study was conducted on twelve healthy Osemi rams, 4 months old, located at the farm of Faculty of Agriculture, Minia University. The body weight of rams was (17.6 ± 1.26 kg). 2.2. Ration: Basal diet was formed from commercial normal diet, containing corn 42%, soybean 16% and bran 42% with adding 0.03%…

aspirated directly into the flame of atomic absorption spectrometry. The proposed method permitted a large enrichment factor of 105. The precision of the method was ±2.3% (n=8 and C=2.0 µg mL-1) and the limit of detection (3Sbl) was 0.1 ng mL-1. The calibration curve for gold is linear between 0.45 ng mL-1 to 10.0 µg mL-1 in initial…

In his essay “The Loser Edit”, Colson Whitehead explores the idea of a “loser edit”, which he defines as a narrative that strives to capture someone’s life to fit a certain edit. The edit puts a spotlight on our flaws through reality tv, social media, and real life situations. Whitehead explains that the loser and winner edit “clasp meaning onto experience”, through its control over our actions or reactions in everyday life. In this essay, Whitehead argues about the harm that the loser edit…

The Reaction of a food dye with bleach Introduction The overall purpose of the experiment was to determine the order in respect to the blue dye and the rate constant (K). With these found however, the overall rate law in the reaction between blue food coloring and the bleaching agent within commercial Clorox can be found. The orders in a rate law equation represent the relationship between the concentration of a given element or molecule and the overall rate, for example, when a reaction in…

Gas chromatography (GC) is a chromatography technique where the separation of individual components (called analytes) from a sample relies on their differing distribution between the mobile phase and a stationary phase. The mobile phase is what carries the analyte (components being analysed) through the stationary phase and in GC, it is an inert gas, (usually helium or nitrogen). The gas must be inert so it will not react with the samples to give a false reading. The stationary phase is the…

In this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…

DISCUSSION 6.1 FTIR SPECTROSCOPY It was observed from the FTIR graph that there was no shifting of peaks of metronidazole i,e., characteristic peak of the amine group (N-H streching) present in imidazole nucleus at 1030 cm-1 and presence of NH2 group at 3298 cm-1 in formulation. Hence, there was no interaction between drug and polymer. 6.2 METRONIDAZOLE MICROSPHERES 6.2.1 Optimization of speed (rpm) for preparation of microspheres Metronidazole microspheres were prepared using emulsion…
