The following sentence appears in the abstract of an article describing a new analytical method, involving HPLC and AFS for the determination of arsenic compounds in rice: “The method was applied to a market basket of rice samples.” What would you expect to find in the Results and Discussion section of the article to support this statement?

a. A table showing the results of the analysis of several rice samples purchase at a local supermarket.

b. The results of experiments in which known amounts of different arsenic compounds were added to rice samples, which were then analyzed.

c. The results of several different methods that were evaluated for the extraction of the arsenic compounds into solution.

d. A table showing the results of the analysis of some certified reference materials that were in not significantly different from the values on the certificate.

e. Several figures showing the chromatograms obtained when some certified reference materials were analyzed by HPLC.

Expert Solution

The meaning of the sentence ' This method was applied to a market basket of rice samples' means rice samples was collected from market and then the method was applied onto it to find arsenic compounds in it.

If arsenic is present in the soil , all plants absorb it but rice can absorb arsenic from irrigation water also. Again rice absorbs more arsenic than other. So presence of arsenic in rice sample indicates there is arsenic contaminated water.

Therefore in the result and discussion section of the article

there should be a table showing the results of the analysis of several rice samples purchased at a local supermarket.

hence option a is right.

Examine the following abstract: “In this study, we investigate the behavior of new nano ZrO2 and Al2O3-13 wt.% TiO2 thermal sprayed coatings on commercially pure (cp)-Ti (grade 4) and titanium alloy substrates. Friction and wear tests against Al2O3 balls showed that the wear resistance of Al2O3-13 wt.% TiO2 is better than that ZrO2 coating. Both plasma sprayings have similar abrasive wear behavior; however, the average friction coefficient is higher for alumina-titania coating. Electrochemical tests, open circuit potential monitoring and potentiodynamic...

For the following scenarios involving HPLC, state whether the internal standard method, or the standard addition method would be more appropriate and why. 1)You use a multi-step method (including extraction steps) to prepare your sample prior to analysis. 2)You are analysing a sampleof industrial waste. It is a very complex sample which you know will contain many unknown impurities. 3)Yourdetector response varies slightly with temperature, however yourinstrument is not temperature controlled.
