Spectrophotometry was used in the lab to determine whether non-magnetized zeolite‚ magnetized zeolite‚ or charcoal was the more effective sequestration agent for Procion Red Dye. A calibration curve was created with the known concentrations and the absorbances of the Procion Red Dye dilutions at λmax. The slope of the calibration curve was used to determine the concentration of the analytes. As a result‚ charcoal was shown to be the more effective sequestration agent. Introduction PAHs‚ polycyclic

The primary sources of dye have been nature‚ with the dyes being extracted from animals or plants. In the last 150 years‚ humans have produced artificial dyes to

Punk Rock‚ which began in the mid 1970’s‚ began as a fad and quickly became a phenomenon that changed the music industry forever. Punk Rock was a new sound that came from a combination of rock and pop music. Punk was very different from mainstream music and along with this new sound‚ an entire subculture started to form. The focus of this paper is on the early development of punk rock‚ the bands and musicians who started the new sound‚ the subculture that was influenced by the punk rock movement

separate the Red 40 and Blue 1 dyes inside of grape flavored Kool-Aid. It was determined that the 5% isopropanol will remove the Red 40 dye from the stationary phase. The 28% isopropanol will remove the Blue 1 dye from the stationary phase. The more polar molecule is removed with the more polar mobile phase‚ the less polar molecule is removed with the less polar mobile phase. This is where the principle “like dissolves like‚” plays a factor in the separation of the dyes. Both molecules are relatively

characteristics of the flow could be determined. The rock inside the stilling tank are to calm the inflow water so that there will not be any turbulence interfere with the experiment. The water inlet and outlet valve and dye injector utilized to generate the required flow. A dye injection system is installed on top of the header tank so that the pattern of the flow can be visualized. The characteristic of the flow is observed‚ there are laminar‚ transition and turbulent flow. The volume of water

Title: Using Natural Dyes form Plants In Producing Colored Paste III. Introduction: Our project is made from the raw materials such as starch‚ alum and annatto seeds. One of our reasons in making this project is it can help students save money because our product can be a substitute for glue

are actually drinking‚ and how much of that drink is contaminated with dye? In this experiment‚ with the use of a spectrophotometer‚ the amount of concentrated dye in three drinks will be tested. First‚ the dye itself will be examined to see what the optimal wavelength and absorbance will be when created in a serial solution. Red Dye 40 was the prime object that will be studied in this lab because it is one of the most common dyes in every day drinks. Before performing any experiment though‚ it is important

pollution problems worldwide . Dye is one of the most common organics in wastewaters discharged from textile industries. The effluents from textile dyeing industry contain many organic pollutants and cause serious environmental problems due to their color‚ high chemical oxygen demand and nonbiodegradability. Reactive dyes from textile and dyeing industries pose grave environmental problem as it gives toxicity that can be harmful to the living organism. Reactive dyes are highly water soluble‚ nondegradable
