Purification of Poisons

Purification of Poisons: Forensic Chemical Determination Stage

Determining the presence of poisons in the body is an important task of forensic medicine, which can help in the investigation of murders, suicides and accidents associated with intoxication or poisoning. One of the stages in the forensic chemical determination of poisons is their purification, which includes the removal of impurities and separation.

The first step in the purification procedure for poisons is to isolate them from biological materials such as blood, urine or gastric contents. This can be achieved by extraction, distillation or filtration, depending on the properties of the poison and the material in which it is present.

After isolating the venom, the next step is to remove contaminants such as proteins, lipids and carbohydrates that may interfere with the test results. This can be achieved by treating the venom with various reagents that can bind or destroy impurities while the venom remains unchanged.

Finally, poisons can be separated into their components to facilitate further analysis. This can be achieved by chromatography, electrophoresis, or other separation techniques that separate poisons based on their physical and chemical properties.

Although the purification of poisons can be time-consuming and resource-intensive, it is an important step in forensic chemistry to provide accurate test results and answer questions about the presence of poisons in the body.

Purification of poisons is a very important part of forensic chemistry research. In this process, it is necessary to separate the poison from other substances present in the test object, allowing further identification of the substance.

Various methods are used to purify poisons, such as adsorption, stripping, distillation and chromatography.
