Abstract:
      Detection of 11 possible dopants of natural latex，including sugar，salt，starch，urea，ammonium chloride，ammonium sulfate，sodium bicarbonate，calcium carbonate，talc，kaolin，and lime powder， which affected the dry rubber content measurement of natural latex，was investigated. The qualitative and quantitative analysis methods for natural latex doped with kaolin，calcium carbonate，talc and starch were mainly discussed. The aim of this paper was to establish a set of simple，rapid，accurate and feasible detection methods for the doped natural latex，which was helpful for the evaluation of the quality of natural latex in rubber collection stations and rubber processing enterprises..
