1. A process for removing arsine from a hydrocarbon mixture having 2 to 4 carbon atoms, comprising contacting the hydrocarbon mixture having 2 to 4 carbon atoms with an adsorbent, wherein said adsorbent is a metal organic frameworks (MOFs) comprising:
a) at least 1 transition metal selected from a group 1B metal, and
b) an organic ligand selected from a dicarboxylic acid compound or a tricarboxylic acid compound,
wherein said adsorbent is subjected to treatment with alcohol prior to contacting the hydrocarbon mixture having 2 to 4 carbon atoms with the adsorbent.
