Elemental sulfur present in fluids such as refined petroleum products, e.g., gasoline, jet, diesel, kerosene or fuel additives such as ethers, is removed from such fluids by contacting the contaminated fluid with an adsorbent of Mg2AlNO3 or Mg3AlNO3 or by adding to the fluids a quantity of hydro-carbyl mercaptan and passing the resulting mixture through an adsorbent selected from the group consisting of alumina, bayerite, brucite and hydrotalcite like materials of the formula M x 2+ M y 3+ (OH)2x+3y-z (NO3) MH2O wherein M2+ is Magnesium, M3+ is aluminum, and x, y and z are values from 1 to 6 and m is the number of waters of hydration.
