Description In the past few decades, a number of elegant instrumental techniques are
reported which are rapid, selective and having a high degree of accuracy.
Spectrophotometric methods of analysis is an excellent tool, which is widely used for
the determination of wide variety of materials. The technique is the most commonly
used method for metal analysis. Achievement of high accuracy and precision coupled
with the cost effectiveness is the most important advantage of visual
spectrophotometry. Therefore the availability of spectrophotometer made this
technique indispensable to the modern analytical chemists.
Analytical chemistry plays a vital role in many research areas in chemistry,
biochemistry, biology, geology, and other sciences and analytical chemist has a very
important role in modern industrialized society. Thus most industries rely upon both
qualitative and quantitative chemical analysis to ensure that the raw materials used
meet certain specifications, and also to check the quality of the final product. Analysts
have developed large number of instrumental techniques and these techniques are
extremely sensitive and can yield results rapidly to a high degree of accuracy. Among
these instrumental analytical techniques, spectrophotometric technique occupies a
unique position because of its simplicity, sensitivity, accuracy and rapidity. The
availability of spectrophotometer made this technique indispensable to the modern
analytical chemists. It is the most important method for determining metals in alloys,
minerals and complexes, owing to its sensitivity and selectivity. Spectrophotometry
offers the advantage of having calibration graphs that are linear over a wide range.
These instruments are with digital readouts or connected to a computer, which
provides a high degree of accuracy and an excellent way to determine the metal ion in
parts per million levels. The limitation to its use is set by the degrees of interference
from other metal ions.
