Australian Paper Manufacturers Introduction Australian Paper Manufacturers (APM) and Paper Company of Australia (PCA) were subsidiaries of the major Australian Corporations during 1986. APM specialized in producing paper packaging whereas PCA produced fine paper. Production activities were performed using chemical processes. The case mainly discusses how APM and PCA faced with environmental issues concerning the spilling of toxic chemicals produced by these chemical transformation processes.

Chromatography of Food Dye Chem 180-DL3 Abstract: The goal of this experiment was to use different dyes to determine the Rf value. Chromatography is done to determine the presence of a mixture in a substance. In this experiment different dyes were used such as McCormick food coloring‚ M&M’s‚ Kool-Aid‚ and the dyes that came with the lab kit. Experiment and Observation: In this experiment a 50mL beaker was filled with luke warm water and a pinch of salt water was dissolved in it

Waste banana plant (Musa sp.) Trunks as an Alternative source of pulp for paper making Introduction Background of the study Edible Banana (Musa sp.) the plant is a gigantic herb that springs from an underground stem‚ or rhizome‚ to form a false trunk 3–6 meters (10–20 feet) high (Encyclopedia Britannica‚ 2006). Bananas cannot be grown anywhere because they are very sensitive to strong winds‚ hence‚ if planted on open areas‚ one must use windbreakers for the banana plant not to be harmed

Paper chromatography is a useful technique for separating and identifying pigments and other molecules from cell extracts that contain a complex mixture of molecules. The solvent moves up the paper by capillary action‚ which occurs as a result of the attraction of solvent molecules to the paper and the attraction of solvent molecules to one another. As the solvent moves up the paper‚ it carries along any substances dissolved in it. The pigments are carried along at different rates because they

Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy

6. FIRST DERIVATIVE ZERO CROSSING METHOD 6.1. ABSTRACT: Simple‚ specific‚ accurate and precise 1st order derivative zero-crossing spectroscopic method was developed for simultaneous determination of PHENYLEPHRINE and EBASTINE from their binary mixture. In this 1st derivative zero-crossing spectroscopic method the amplitudes of the 1st order derivative of the spectra of the binary mixture containing PHE and EBS were measured at 252.2 nm (zero crossing of EBS) for determination of PHE and at 274.8
