Unformatted text preview: 1 The objective of this study was to determine the percentages of cis, trans and vinyl formation in the polymeric chains of polybutadiene by FT–IR spectrophotometer. All absorption peaks in the mid -range -1 -1 -1 IR (400 – 4000 cm ) have been investigated. In particular, peaks at frequencies of 966 cm , 912 cm -1 and 735 cm which were designated for quantitative analysis of the respective trans, vinyl and cis. Peak -1 area in the frequencies range of 833 – 635 cm have been used to prepare calibration plots for the cis -1 isomer and the results obtained were compared with those obtained from the analysis at 735 cm . The effects of type of solvents used towards the calibration curves have also been studied. POLY-O4 A STUDY OF ROLE OF pH AND ITS FUZZIFICATION IN PHENOL REMOVAL IN WASTE TREATMENT PROCESSES 1 Khokhar, ZH, Al-Harthi, MA., Aburraheem A. and Shawabkeh RA 1 2 1 1 Department of Chemical Engineering, KFUPM, Dhahran -31261, Saudi Arabia 2 RI, KFUPM, Dhahran-31261, Saudi Arabia E-mail: mamdouh@kfupm.edu.sa In this paper, a focused study is presented of the work done in the field of phenol removal in waste treatment processes in recent years and discussed the highly important parameter which is found to be the pH. Therefore, it is tried to concentrate the literature review and studies around pH. It is noted that phenol is made of 'ph' and 'enol' and is defined as an organic compound containing a hydroxyl group bonded to a carbon atom, which in turn is doubly bonded to another carbon atom. pH is found to be a controlling factor. Fuzzy logic approach is applied to model results of a case study selecting time and temperature with pH for biosorption capacity of phenol. It is also found that the approach is good to further expand the study for more parameters and for more studies. 220 3rd ICYC 2010 Universiti Sains Malaysia POLY-O5 23rd-25th June 2010 TREATED CHITOSAN FILLED POLYPROPYLENE COMPOSITES ON THERMAL PROPERTIES A Faisal, H Salmah and H Kamarudin School of Material Engineering, Universiti Ma...
