The Importance of Chemistry in Daily LifeMost people have chosen to write their essay about how chemistry has played an important role in everyday I have chosen to ask， how doesn't it play a role in everyday life? The simple fact is that chemistry plays an important role in every person's daily activities from the moment we're So what role does chemistry really play in everyday life? Well， this involvement usually begins first thing each Most people wake up to an alarm or These common household items contain batteries， which make them very chemically These batteries contain positive and negative The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese The negative electrode is made of Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household Things like household cleaners and water purification systems are vitally dependent on Without chemistry something as simple as scrubbing a toilet without fear of severe burns or small explosions might not be Next， though it isn?t widely known， chemistry is also heavily involved with the manufacturing of things such as makeup and Each time you bathe you are witnessing chemistry at Chemicals such as cetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair and Without chemistry， these materials (or combinations of these materials) might be hazardous or might not The chemical coloring agents used in makeup and nail polish would not be possible without an understanding of the chemicals Almost anything you do during the course of a normal day involves chemistry in some The gas and tires in cars we drive， the makeup we put on our faces， the soaps and cleaners used everyday， burning wood or other fossil fuels， chemistry is all around you each and every The associations are practically So， as you go about your daily activities， remember to thank As my teacher always says， remember， "CHEMISTRY IS LIFE!"
有机化学英语论文Abstract In this work the effects of the microporosity and chemical surfaceof polymeric adsorbents on adsorptive properties of phenol Textural parameters of four kinds of polymeric resins namely AB-8 D4006 NKA-II and D16 resin were separately measuredby ASAP The surface chemistry of these polymeric resins was determined by means of inverse gaschromatography (IGC) and diffusereflectance infrared Fourier transform spectroscopy (DRIFTS) Static equilibrium adsorption experiments were carried out to obtain theisotherms of phenol on the polymeric It was shown that NKA-II and AB-8 resin possessed relatively high BET surface areas andmicropore volumes while D4006 and D16 resin possessed comparatively low BET surface areas and micropore The results of IGCexperiments revealed that NKA-II resin had extraordinary high specific component of the free energy of adsorption both for polar acetone andbenzene probe and thus extraordinary strong surface polarity compared to the other polymeric It was also found that the isotherm ofphenol on NKA-II was much higher than that on the other polymeric resins due to its strongest surface polarity and largest micropore volumeamong four kinds of These experimental observations indicated that adsorption of phenol on the polymeric resins depended greatly ontheir microporosity and surface The well-developed microporosity and the strong surface polarity would improve the adsorptionof phenol on the polymeric 2004 Elsevier BV All rights Keywords: Polymeric resin; Phenol; Porosity; Surface chemistry; Inverse gas chromatography
