| Abstract: | A simplified strip-concentration apparatus could be connected with GC was developed successfully in our lab. Under suitable conditions,it could be used to analyse the trace amount of volatile alcoholates in the contaninated condensates of pulping mills.The detection limits are lowing to 1 to 10μg/L, the standard deviations are lower than 0.01 and the recoveries are higher than 81%. |
