The ocean contains around eighty elements of the periodic table and uranium is also one among them, with a uniform
concentration of 3.3 ppb and a relative abundance factor of 23. With a large coastline, India has a large stake in exploiting
the 4 billion tonnes of uranium locked in seawater. The development of radiation grafting techniques, which are useful in
incorporating the required functional groups, has led to more efficient adsorbent preparations in various geometrical
configurations. Separation based on a polymeric adsorbent is becoming an increasingly popular technique for the extraction
of trace heavy metals from seawater. Radiation grafting has provided definite advantages over chemical grafting. Studies
related to thermally bonded non woven porous polypropylene fiber sheet substrate characterization and parameters to
incorporate specific groups such as acrylonitrile (AN) into polymer back bones have been investigated. The grafted
polyacrylonitrile chains were chemically modified to convert acrylonitrile group into an amidoxime group, a chelating group
responsible for heavy metal uptake from seawater/brine. The present work has been undertaken to concentrate heavy metal
ions from lean solutions from constant potential sources only. A scheme was designed and developed for investigation of the
recovery of heavy metal ions such as uranium and vanadium from seawater.
