Abstract
Provided is a method of making colloidal selenium nanoparticles. The method includes the steps as follows: Step (A): providing a reducing agent and an aqueous solution containing a selenium precursor; Step (B): mixing the aqueous solution containing the selenium precursor and the reducing agent to form a mixture solution in a reaction vessel and heating the mixture solution to undergo a reduction reaction and produce a composition containing selenium nanoparticles, residues and a gas, and guiding the gas out of the reaction vessel, wherein an amount of the residues is less than 20% by volume of the mixture solution; and Step (C): dispersing the selenium nanoparticles with a medium to obtain the colloidal selenium nanoparticles. The method has advantages of simplicity, safety, time-effectiveness, cost-effectiveness, high yield and eco-friendliness.
