Spectrophotometric Metal Ion Analysis
Spectrophotometric metal ion analysis is a technique that uses the absorption or emission of light to determine the concentration of metal ions in a sample. This technique is based on the principle that metal ions can absorb or emit light at specific wavelengths, which can be used to identify and quantify the metal ions present in a sample.
Spectrophotometers are used to measure the absorption or emission of light by a sample. There are two main types of spectrophotometers: UV-Vis spectrophotometers and atomic absorption spectrophotometers. UV-Vis spectrophotometers measure the absorption of light in the ultraviolet and visible regions of the spectrum, while atomic absorption spectrophotometers measure the absorption of light by atoms in the sample.
Spectrophotometric metal ion analysis is used in a variety of fields, including environmental monitoring, industrial chemistry, and clinical chemistry. In environmental monitoring, spectrophotometric metal ion analysis is used to determine the concentration of metal ions in water, soil, and air samples.
In industrial chemistry, spectrophotometric metal ion analysis is used to control the concentration of metal ions in industrial processes. In clinical chemistry, spectrophotometric metal ion analysis is used to determine the concentration of metal ions in blood and urine samples.

| Sample | Absorbance | Concentration (mg/L) |
|---|---|---|
| 1 | 0.250 | 10.0 |
| 2 | 0.500 | 20.0 |
| 3 | 0.750 | 30.0 |
Data Analysis and Interpretation, Experiment 35 spectrophotometric metal ion analysis
The data obtained in Experiment 35 can be used to determine the concentration of copper ions in the sample. The absorbance of the sample is directly proportional to the concentration of the metal ion in the sample. The following equation can be used to calculate the concentration of the metal ion in the sample:
Concentration (mg/L) = Absorbance / (ε – l)
where:
- ε is the molar absorptivity of the metal ion
- l is the path length of the cuvette
The molar absorptivity of copper ions is 1.35 x 10 4L/(mol·cm) at a wavelength of 635 nm. The path length of the cuvette is 1 cm. The absorbance of the sample is 0. 250. The concentration of copper ions in the sample can be calculated as follows:
Concentration (mg/L) = 0.250 / (1.35 x 10 4L/(mol·cm) – 1 cm) = 10.0 mg/L
The results of Experiment 35 show that the concentration of copper ions in the sample is 10.0 mg/L.
There are a number of potential sources of error in Experiment 35. These sources of error include:
- Errors in the preparation of the sample
- Errors in the measurement of the absorbance
- Errors in the calculation of the concentration
These sources of error can be minimized by carefully following the experimental procedures and by using accurate equipment.
