Chromatographic analysis of inorganic anion,cation and GC-MS analysis of organic compounds in salt brine from Xuwen

We measured the common anions and cations in Xuwen sea salt brine using anion and cation spectra,and analysed the organic matters extracted with aether brine using GC-MS.The results showed that the concentrations of anion Cl-,Br-,SO42-were 204.00,3.56 and 74.20 g·L-1,respectively,and PO43-was not detected(concentration less than 0.30 g·L-1);The concentrations of cation Na+,K+,Ca2+,Mg2+ were 28.50,19.30,0.50 and 83.00 g·L-1,respectively;The organic matters extracted with aether were mainly alkanes,alkenes,alcohols,esters,ketones,ethers and anhydrides substances.
