A method for removing silica from an aqueous solution is provided. The method includes steps of flowing the aqueous solution into an electro-Fenton reactor, wherein the reactor comprises one or more electrodes in a bipolar arrangement positioned between a monopolar iron anode and a monopolar cathode; applying an electric current to the aqueous solution such that silica aggregates form on ferric hydroxide; and removing the silica aggregates from the aqueous solution.

Neutron dosimetry is performed using a water-based chemical dosimeter measurement of radiation-induced reduction of hexavalent Cr (VI) to trivalent Cr (III) in the presence of sodium formate at pH 9.2. Neutron absorbance material (Gd-157) increases the neutron interaction with the dosimeter. When a monoenergetic beam with 0.025 eV energy was used as a thermal neutron source 1 mol/dmof Gadolinium gave the best outcome while surrounding the dosimeter with 1 cm Gadolinium sheets. The dosimeter was giving acceptable readings when using thermal neutrons.
