Green Chemistry Laboratory Manual for General Chemistry


Book Description

Green chemistry involves designing novel ways to create and synthesize products and implement processes that will eliminate or greatly reduce negative environmental impacts. Providing educational laboratory materials that challenge students with the customary topics found in a general chemistry laboratory manual, this lab manual enables students to see how green chemistry principles can be applied to real-world issues. Following a consistent format, each lab experiment includes objectives, prelab questions, and detailed step-by-step procedures for performing the experiments. Additional questions encourage further research about how green chemistry principles compare with traditional, more hazardous experimental methods.

This is a working manual, meant to be kept by your side in the lab, not on the shelf in an office or library. You can bend it, you can lay it flat, you can take it anywhere you do your job. Useful and practical Drinking Water Chemistry: A Laboratory Manual provides the information you need to perform tests, understand the results, apply them to the determination of water quality before and after treatment, and troubleshoot any problems.




Laboratory Experiments in Environmental Chemistry


Book Description

This lab manual provides an interdisciplinary collection of 23 extensively tested environmental chemistry experiments — with extensive introductory background material for each experiment. It covers a broad range of methods and provides detailed instructions on calculation of results. Experiments involve, for example: inorganic and organic profile of sediment and soil cores; the pH of environmental waters and buffer capacity; alkalinity of streams and lakes; trace levels of ions in natural waters; conductivity of natural waters; cloride ion in natural waters; colorimetry and absorption spectra; metals in natural waters and in sediments; atomic absorption spectrometry; the chemical oxygen demand of natural waters and wastewaters; the fluorimetric determination of polycyclic aromatic hydrocarbons; environmental hydrocarbons; air sampling-particulates in urban air; carbon dioxide in the atmosphere; acid rain; decomposition of pollutants with an application to plasticizers, and detergents. For chemists and technicians with environmental agencies.




Experiments in Environmental Chemistry


Book Description

Experiments in Environmental Chemistry presents experimental activities that provide practical, first hand experience in the observation of chemical processes occurring in the environment. A variety of techniques with applications in governmental laboratories, industry, and research are described. The experiments are divided into five parts: biochemical processes in aquatic systems; toxic substances in the environment; food additives and contaminants; chemical ecology; and field surveys. This book is divided into five sections and begins with a discussion on the transformations of carbon, nitrogen, phosphorus, and energy in aquatic systems. Various aspects of environmental chemistry including photosynthesis, respiration, biogeochemical cycling, primary production, plant nutrients, water quality, eutrophication, and wastewater treatment are considered. The next section focuses on a wide assortment of environmental contaminants in terms of their behavior and occurrence in various sectors of the environment. In this section, the reader is introduced to gas chromatography, atomic absorption spectroscopy, thin layer chromotography, column chromatography, and techniques for the measurement of atmospheric contaminants. Food and the occurrence of foreign substances that result from deliberate additions or other processes are also analyzed, along with chemical compounds such as allelochemicals, pheromones, and chemical defense substances. This monograph will be a valuable resource for environmental chemists.
