The nitrogen content in imported recycled plastic particles was determined by elemental analyzer method and Kjeldahl method, respectively, and the acrylonitrile content was obtained by conversion to obtain the information on the consistency of polymer composition in recycled plastic particles. Two specific cases judged by this method were given. This method was available to provide a creative idea and method for the identification of solid waste characteristic of recycled engineering plastic particles containing acrylonitrile monomeric units such as acrylonitrile-styrene copolymer (SAN) recycled particles, acrylonitrile-butadiene-styrene copolymer (ABS) recycled particles, PC/ABS alloy recycled particles, PBT/ABS alloy recycled particles, PMMA/AS alloy recycled particles.
