Method of removing arsenic from a liquid
A method for removing arsenic from a liquid includes adding a two-dimensional metal carbide adsorbent to the liquid to adsorb the arsenic from the liquid. The two-dimensional metal carbide adsorbent can include at least one MXene, having the formula M n+1 X n , where n=1, 2 or 3, where M is an early transition metal, such as scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo) or the like, and X is either carbon or nitrogen. The MXene may be Ti 3 C 2 .
1. A method of removing arsenic from a liquid, consisting of the steps of:
providing an MXene, the MXene consists of Ti 3 C 2 wherein the step of providing the MXene consists of room temperature exfoliation of Titanium (III) Aluminum Carbide (II) (Ti 3 AlC 2 ) using hydrofluoric (HF) acid; and
adding the MXene to a liquid, the MXene adsorbing arsenic from the liquid.
2. The method of removing arsenic from a liquid as recited in claim 1 , wherein the liquid comprises water.
3. The method removing arsenic from a liquid as recited in claim 1 , wherein the liquid comprises a solution including lead (Pb) and chromium (Cr (VI)).
