The first peak with a wavelength of 2952.44cm-1 was found to have a literature value of 2840-3000cm-1. This particular peak can be identified as an alkane functional group, displaying a methyl C-H symmetric stretch. This functional group was at the core of the compound The C-H bonds revealed minimal polarity. The second recorded peak was measured at 1779.80cm-1. This peak was classified as an anhydride functional group, having a C=O stretch, with a strong and sharp peak.
When analyzing the R2 values of Graphs 1 and 2, their respective R2 values of 0.9956 and 0.99062 indicate the regression of each trend line fits the data points extremely well. From these consistent graphs, the k values of 1-propanol and 2-propanol were identified to be 0.5753 per minutes and 0.4662 per minutes, correspondingly. The half-lives of each were then calculated: t1/2 of 1-propanol = 1.2048 minutes; t1/2 of 2-propanol = 1.4868 minutes. These oxidation techniques are not only often used in the organic chemistry lab, but are frequently used in various scientific fields and are even used to create home care products. Ultimately, this particular lab resulted in the collection of very plausible
In addition, phenolphthalein was added as an indicator. The aliquots were titrated against sodium hydroxide (NaOH) solution until end point was reached, after which volume of NaOH consumed was recorded. The value of the rate constant, k, obtained was 0.0002 s-1. The experiment was then repeated with 40/60 V/V isopropanol/water mixture and a larger value of k = 0.0007 s-1 was obtained. We concluded that the rate of hydrolysis of (CH3)3CCl is directly proportional to water content in the solvent mixture.
This adsorbent were added into 50ml of arsenate solution with an as(v) concentration of 2mg for evaluation of adsorption efficiency after shaking of solution at room temp. for 24 hr sample solution filtered through a .45 micro meter for adsorption isotherm experiments conducted t pH 4 and pH effect experiment are done ranging from 1.8 to 11.6 at a constant concentration 2mg/l. Batch process is conducted to obtained the pH of point of zero charge (pHpzc) of the RACF and the MACF. Different amount of NaNO3 solutions of 1mili M with several pH values and prepared with mixing diluted HNO3 or NaOH . ACF cloths has 0.05 g weight was added into 18 mL NaNO3 solutions.
In this experiment, absorbance at A400 was directly proportional to the number of moles of p-nitrophenol. This shows that there is a linear relationship between the absorbance and the number of moles of p-nitrophenol, which later also shows that there is a linear relationship between the absorbance and the concentration of the p-nitrophenol, as the number of moles of p-nitrophenol will increased when the concentration of p-nitrophenol increased. The R2 value obtained for the standard curve is 0.9997, which indicates that the data obtained fit the line of best fit, showing that the data are accurate. The values of absorbance per µmol of p-nitrophenol were then obtained from the gradient of the curve, which will later be used in calculation in determining the enzyme activity. Based on Graph 3, it was shown that the enzyme activity of alkaline phosphatase increased with the increase of MgCl2
This supports the isolated product is majority made of the desired product and is largely pure. Mass spectrometry of the crude product shows the molecular ion peak is 162.1, which is the largest fragment in the mass spectrum (Figure 4) and corresponds to the molecular weight of methyl trans-cinnamate (Table 1). The base peak is 131, inferring the fragment lost is 31 m/z in size. This 31 m/z matches the OCH3 fragment of the ester, and would not result from a trans-cinnamic acid. This is evidence the product was successfully
This transformation has been observed by shifting of diffraction angle of layered titanates from 2θ = 11.4° to higher diffraction angle (2θ =14.1°). Similar results were reported by Suzuki and Yoshikawa  and Morgado et al.  in the thermal stability study on titanate nanotube. The diffraction peak (at 2θ=27.5°) related to added CN was not observed in the PXRD pattern, because it is merged with the TiO2 (B) phase peak at 28.6°. Further the intensity of peak at 28.6° is increasing with increase in the amount of CN loading.
For treatment 3, the solution was 0.15 HgCl2 , 60%, 40% and 20% Clorox. A final cutting for each explant was 1.5 -2cm. The explants were transferred into NDM with 0.2% activated charcoal and 1mg/L BAP hormones. Data free contamination, survival and shoot initial rate percentage were recorded after 60 day of culture. The next experiment, studied the effect of BAP (0, 0.5, 1, 3, 6 and 9mg/L) on shoot regeneration.
As a complementary technique, FTIR was applied to obtain information about the chemical compounds in the studied pigment samples. Figure 5(b) shows an FTIR spectrum recorded on the blue pigment sample (Ha. A). Egyptian blue pigment represents characteristic peaks lying mainly between 1280 and 1000 cm1, which are attributed to SiOSi stretching vibrations and mainly the intense bands at 1138 and 1054 cm1. Quartz was deemed to be present owing to the existence of the corresponding peak at 463 cm1 (SiO).
MATAG inflorescence were collected from Department of Agriculture Terengganu’s farm. The samples were stored in ice-box to maintain its freshness prior to culture. B. Optimization of Sterilization Procedure The rachillae bearing inflorescence were cut off from the spadices and then were washed under run-ning tap water for 15 to 20 minutes to remove dirt and debris. The male inflorescence was isolated from rachillae and subjected to three different method of sterilization (as described in Table 1). C. Media Compositions and Growth Conditions The basal media used for this experiment were Y3 media (Eeuwens, 1976).
