crypto-sporidiosis and cholera. Water refilling stations can help address the water contamination problem. Here are questions to ask before patronizing a water refilling station. 1. Does the water refilling station have a performance data sheet for its purification or filtration system? This sheet lists all the contaminants the system is certified to remove and to what degree. It also contains certifications the company may have. It is not the number of stages the water goes through a process that makes

To the surprisingly inventive uses for banana peels -- which include polishing silverware‚ leather shoes‚ and the leaves of house plants -- scientists have added purification of drinking water contaminated with potentially toxic metals. Their report‚ which concludes that minced banana peel performs better than an array of other purification materials‚ appears in ACS’s journal Industrial & Engineering Chemistry Research. Gustavo Castro and colleagues note that mining processes‚ runoff from farms

artesian water‚ may be more pure‚ but there is no proof that it is any cleaner than water from the tap or ground water. Water that comes from the tap‚ and is bottled‚ goes through a purification process before it hits the shelves. There are a number of ways to purify water and four are mentioned here in this article. Purification is the process in which bottling companies remove any minerals‚ particles‚ and other contaminants to make it safe to drink for the consumer. Bottled water‚ however‚ is not

normally in higher need of purification than that produced from natural gas‚ especially sulphur compounds must be removed before the methanol synthesis to protect the catalysts from poisoning. Methanol purification Regardless of the synthesis method the crude methanol produced contains many impurities.The largest impurity is normally water which can be a high as 18 %. The first stage in a common two-step purification process is to remove the low boiling purifications‚ typically called “light ends”

The experiment consists of 5 steps—Inoculation‚ fermentation‚ cell lysis‚ inclusion body solubilization‚ and peptide purification. In the first two steps‚ E coli with Snake 6 peptides is cultivated. Ultraviolet–visible spectroscopy (UV-vis) is used to quantify bacteria through detection of their optical density (O.D.). After reaching a certain concentration in the fermentation batch‚ inclusion bodies (IBs) are extracted from these E coli by adding Bugbuster lysis solution and lysozyme. Polyacrylamide

INTRODUCTORY AND IMPORTANCE OF ORGANIC CHEMISTRY Organic chemistry is the study of the compounds of carbon. Carbon compounds are far more numerous than those of other elements because carbon are able to bond together to form a wide range of chains and rings. The subject is named organic chemistry because living organisms are composed

Experiment 2 and 3: Synthesis of Aspirin and Determination of Melting Point A. Abstract Aspirin is the common name for the compound acetylsalicylic acid‚ widely used as a fever reducer and as a pain killer. The first part of the experiment aims to synthesize aspirin from the reaction of salicylic acid with acetic anhydride with the aid of phosphoric acid as a catalyst. The second part of the experiment aims to assess the purity of aspirin through the determination of its melting point and
