Phosphate ions interfere with the atomic absorption spectrometric determination of calcium due to the formation of calcium phosphate that does not easily break up into atoms in the natural gas/air flame. The interference can be minimized by doing the following except A. using a natural gas/oxygen flame B. adding an excess amount of strontium chloride C. adding EDTA to the sample D. adding an excess amount of sodium sulfate E. adding an excess amount of lanthanum(III) chloride

As a forensic toxicologist, you have been given a task on determining amount of cadmium, mercury, chromium, copper and lead metal contents in medicinal herbs using flame atomic absorption spectroscopy (AAS). Hollow cathode lamp (HCL) was selected as radiation source for this analysis. The highest concentration came from lead element followed by chromium and copper, however cadmium and mercury were not detected in the sample. a) Based on your knowledge, conclude whether the above result is valid or not. b) If you are given an option of electrothermal or flame atomizer for above case study, determine which one is suitable and justify your answer.
The measurement of Li in brine (salt water) is used by geochemists to help determine the origin of this fluid in oil fields. Flame atomic absorption of Li is subject to interference by other elements. Atomic absorption of analysis of replicate sample of Li in a brine sample gave results in the table. a. Suggest a reason for the increasing apparent concentration of Li from sample 1 to 2. b. Suggest a reason for the increasing apparent concentration of Li from sample 1 to 3 c. Why do samples 4-6 give a nearly constant result? (What type of interference you think is being eliminated?

UV-Visible spectroscopy is used to determine the content of an analyte in a capsule. Weigh 100.0 mg of the capsule contents (total weight of contents 500 mg), add 2.0 mL of 0.05 M NaOH, filter the flask, and make up to 25.00 mL with NaOH. The measured transmittance of this solution is 33.0%. The analyte standard is prepared by dissolving 10.0 mg of standard in 25.00 mL of 0.05 M NaOH, then taking 10.00 mL of that solution and diluting to a final volume of 50.00 mL where the transmittance is obtained from 44.0%. Calculate the content of the analyte in the capsule.
