I took 5 gram of soil mix it with 20mL of hexane and 20mL of acetone. I put the samples on shaker for 30 min. Then i Centrifuged the vials and took the supernatant and mixed it with DI water then passed it through a separatory funnel to take acetone out. Then i passed the extract through Sodium Sulfate and then i ran the extract on the GC i only got decane out in quantitative analysis and the peaks are weird. The retention time for decane is not matching the calibration curve. The RT shifted a little bit. I dont know if i am doing this wrong. Can anybody help me with better extraction technique and i dont have soxlet appratus. Can anyone help me
For the PAH. Is it necessary to pass the soil extract through Silica gel column? If it is how would it be done. Thank you very much
