TLDR
In this article, a scheme was designed and developed for investigation of the recovery of heavy metal ions such as uranium and vanadium from seawater, and the grafted polyacrylonitrile chains were chemically modified to convert acrylatitrile group into an amidoxime group, a chelating group responsible for heavy metal uptake from seawaters/brine.About:

A study on grafting of acrylonitrile onto high-density polyethylene by the neutron activation analysis technique
TL;DR: In this article, small pieces of high-density polyethylene sheet were dipped into acrylonitrile and exposed to 60Co gamma-rays for grafting, and the degree of grafting was determined, for the first time, by estimating the amount of nitrogen incorporated in the grafted sample using a 14 MeV neutron activation analysis technique.
