Application of Fluorescence Spectroscopy in Chemical Oceanography: Tracing Colored Dissolved Organic Matter (CDOM) Erika Mae A. Espejo 3rd year‚ BS Chemistry‚ University of the Philippines‚ Diliman Abstract Dissolved organic matter (DOM)‚ the fraction passing through a 0.45 µm membrane filter‚ is considered poorly understood mixture of organic polymers because of its complexity. Although it largely influences a lot of biogeochemical processes in aquatic environments‚ its characterization is not

management and personnel‚ three options were proposed: invest additional monies into the Italian division and revive operations‚ target production towards absorption chillers rather than the compression chillers‚ or wait about six months and observe the activity of the economy before making any type of financial decision. Targeting production towards absorption chillers is the best option for Clayton in order to regain its position financially and its competitive position in the market. INTRODUCTION

Mass Determination of Ca‚ Fe and Zn in a multivitamin using Atomic Absorbance Spectroscopy (AAS) and X-Ray Fluorescence Spectroscopy (XRF) ABSTRACT: The purpose of this project was to determine the amount of calcium‚ iron and zinc present in an over the counter multivitamin. This mass was determined using atomic absorption spectroscopy (AAS) and X-ray fluorescence spectroscopy (XRF). For both analytical techniques‚ the method of standard additions was used to compensate for matrix effects.

The purpose of this lab was for students to familiarize and perfect the simple distillation method to produce 4-Methylcyclohexene and to gain experience using an IR spectroscopy to characterize the product of the reaction in favor of equilibrium. B. Results and Discussion: C. Experimental: 24 mL of 4-methylcyclohexanol‚ 5mL of phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer.

Post-Lab Report for Experiment 2: Cooperative Identification of an organic Solid October 6‚ 2013 Introduction: This experiment was focused on the cooperative identification of organic compound by its chemical properties such as: slow melting point‚ mixed melting point‚ Rf values in TLC experiment‚ IR spectrum analysis‚ and H NMR spectra. Such data can provide the the identity of functional groups and the identity of the compound itself. In this experiment

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and
