Polyacrylonitrile (Poly-AN) was modified using two-step conditioning: 1) amidoxime chelation and 2) conversion to carboxylic groups using sodium hydroxide (NaOH). 

Design of experiments (DOE) used to predict trends in uranium adsorption capability with changing factors of second step conditioning. 

Conditioning temperatures above 50 °C and NaOH concentrations >0.5 M are optimum to achieve highest possible uranium adsorption capacity. 

Despite an abundance of other cations, no statistical difference was observed between uptake of uranium from real seawater compared to laboratory prepared simulants and deionised water using bi functionalised Poly-AN
