Abstract: The method of collecting 14C samples in natural water by precipitating was dealt with in this paper. Through experiment the best conditions for precipitating were determined. They are the pH Value of 12 and by adding precipitants two times as much as the equal equivalent, the rate of separating out of inorganic carbon in this work is 99%, and the recovery rate is 97%. The authors suggest that SrCl2 should be replaced as precipitants by CaCl2, then the cost of collecting samples could be reduced.
