CHAPTER 5 DISCUSSION 5.1 Analysis of Trace Metal by FAAS Based on the table (4.3 and 4.4) the trace elements was detected by using the flame atomic absorption spectrophotometry analysis. The trace metal can be detected by the FAAS within 15 seconds to 30 seconds of each soil sample. Before the samples were analysis with the FAAS‚ the blank samples were run in the machine for each element that was being analyzed. Their absorbances were read. The mean of each blank was calculated and

ROHM AND HAAS Joan Macey‚ Rohm and Haas market manager for Metalworking Fluid Biocides‚ was reviewing distributor purchases of Kathon MWX‚ a new biocide that killed microorganisms in metalworking fluids. She found that total sales to distributors for the first five months were 74 boxes against a first-year target of 1.350 boxes. “I have a super product but I can’t sell it” she said. “I am in the process of reviewing our approach of taking this product to market‚ but at this point I am not convinced

The air-flow rate of flotation machine can directly affect the efficiency and quality of products. The main factors affecting the flotation machine air-flow rate can be summarized as the following:1‚ flotation machine impellers and cover the gap: the gap‚ the inflation decreases‚ but the gap is too small will cause the impeller and cover the impact and friction‚ and inflation fell. More appropriate for the gap of 5 to 8 mm2‚ flotation machine into the plasma volume: when the slurry into the impeller

The industrial separation process that I have decided to do is gold separation. Gold separation can be done in a number of ways but there is not always one way to do it‚ but the combination of a couple of these processes to extract pure gold. Gold is obtained form the lithosphere. It is separated from the ore found in the lithosphere. Gold’s symbol is Au. Its atomic number is 79 and has an atomic mass of 196.96655 amu. Its melting point is 1064.43°C‚ while its boiling point is 2807.0 °C. It is

Introduction Silver is a chemical element with atomic number 47 and symbol Ag. It is white‚ soft‚ mallable and ductile metal slightly harder than gold. Silver is extremely flexible‚ this means that it can be converted into both flat sheets and electrical wire. This makes silver is an ideal metal for all kinds of industrial use. Silver occurs in lead‚ Zinc and copper ore deposits. Lead ore is the main source of Silver. In fact‚ 75% of the resources in the world are found in association with other

What is Titanium? It is the 22nd element on the periodic table and labeled Ti. Titanium is strong‚ light‚ and rustproof which is what makes it so important and diverse. The original application for this metal was in the military aerospace industry specifically because of its efficiencies in structural qualities‚ a result of titanium’s strength and density. It has become the metal of choice for many different applications. According to Titanium Industries‚ Inc.‚ Titanium was actually first used

Purpose The purpose of the “Beanium” lab was to determine the average atomic mass of three different isotopes of beanium. During the lab beans were counted to determine mass of the sum of the beans. Each type of bean were weighed separately and then averaged together to determine the average atomic mass of beanium. Materials and Hazards Analytical balance‚ coffee filter‚ pencil‚ paper‚ cup‚ American beans‚ Nigerian beans‚ Mexican beans‚ calculator‚ and paper. Raw Data Bean Total Mass w/ Cup Number
