Metallic poison Extraction|Dry Ashing & Wet Digestion|Forensic Toxicology|Part-23|@SavvyForensicswebsite link..https://savvyforensicsquiz.blogspot.com/CONTAC. Wet digestion with concentrated acids (nitric, perchloric, and sulfuric acid alone or in combination) is the most common sample pretreatment technique, carried out at atmospheric pressure in open systems or at higher pressures in a closed vessel by conductive or microwave heating. Many feedstocks require or can benefit from pre-processing before digestion (e.g., blending, screening, thermal conditioning, etc.) This method produces a linear relationship to absorbance within a mass range of 50 to 300 ng arsenic/arsine reaction. 4. and HNO. Wet digestion is an analytical technique in which we can determine the composition of a sample at its aqueous state. "Partial" and "total" digestion methods can be used in environmental monitoring activities.
Most commonly encountered anions in poisoning cases are bromide, cyanide, fluoride, hypochlorite, nitrate, nitrite .
