Chemical Sequential Extraction

By the chemical sequential extraction method, various chemical speciation of phosphorus were extracted from shallow sediments of Nansi Lake. Aiming at the existing problems of lower concentration of phosphorus, the method combined the original sequential extraction and Mo-Sb Anti spectrophotometric method was improved to reduce the interference caused by stratification and chromogenic reaction. In addition, due to the presence of excess sodium dithionite, the extracting solution need to be diluted during occlude phosphorus (Oc-P) extraction process.
