Title: Principles and Practice of Agarose Gel Electrophorsis Objectives: To detect the size ‚ shape and charge of the each dye solution. Methods: Casting the Agarose Gel In this experiment .8% solution was used. By using a 250ml flask the buffer solution was prepared. Using the equation to make enough solution for the intire lab class the equation had to be multiplyed by five. The contents of this equation were added to the 250ml flask and swirled to evenly distrubute it contents

Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger than 100 nm but after adding sodium lauryl sulphate

Kalamkari the ancient Indian art of painting Kalamkari refers to a method of painting natural dyes onto cotton or silk fabric with a bamboo pen or kalam. The name kalamkari translates as pen (kalam) work (kari) in Hindi/Urdu‚ and was most likely derived from trade relationships between Persian and Indian merchants as early as the 10th century CE. European merchants also had names for this type of fabric decoration: the Portugese called it pintado‚ the Dutch used the name sitz‚ and the British preferred

the lab a better agent for absorbing Procion Red Dye was trying to be found. Using the different dilutions of a stock solution and a spectrophotometer an Absorbance vs. Concentration graph was created and using the trendline from that graph it was determined which agent‚ zeolite‚ magnetic zeolite‚ or charcoal were better at absorbing the dye. From the results collected it was found that charcoal was the best at absorbing the dye‚ when moles of dye per gram of agent used were calculated. Introduction:

Abstract: This experiment explores the technique of absorption spectroscopy. The procedures deal with the wavelengths and absorption of dyes in a sample of grape Kool-aid. The use of Beer’s Law helps to determine values of absorption. Introduction: This experiment demonstrates another technique used in the analysis molecules with light. The study of light absorbed my molecules is known as absorption spectroscopy. This is very easily the opposite of emission spectroscopy because it occurs when

Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure Exercise #1 Step #1: Convert %T (Table 1) to absorbance and prepare a Beer’s law plot using the data. Step #2: Determine the concentration of M of the samples in table 2: A=ebc A= 2-log(%t)

In recent history the black colour comes from an aniline dye. The next recipe indicates that nigrosene (generically‚ a black dye made from oxidised aniline) was domestically procurable in the 1940s. Note that the above recipe uses potassium carbonate (potash) whereas the following recipe uses potassium bicarbonate‚ which is not potash. Imperial
