The reconstruction of formaldehyde analysis in marine sediment of the Gulf of Prigi

Organic material pollution is of particular concern in marine sediments other than inorganic material. The organic material that is suspected as a source of pollutants is formaldehyde. We analyzed the ability of the sediment to absorb organic material, especially formaldehyde. In the first stage of research, we conducted the validation of methods to determine accuracy and precision, and then a preliminary test was carried out to determine whether formaldehyde contained in the sediment. We used the bulk grain size, 200 mesh, 400 mesh to absorb the formaldehyde with concentrations of 0.5%; 0.1%; 0.05% and 0.01% to establish a method using GC-MS. Marine sediment with 200 mesh successfully absorbed and reconstructed the formaldehyde pollutant.
