Cl in sewage sludge may form HCl when burning, and caused acid rain or damaged the chemosphere; meanwhile, it could also enhanced the volatilization of heavy metals. It was important to know the Cl content in sewage sludge. The water extraction method, the Eschka method, the alkali absorption method, the oxygen bomb method, XRF, as well as their combined method were compared and the most suitable method to measure the Cl content in sludge was found. The water extraction- Eschka- alkali absorption method was the best method to measure the Cl content in sewage sludge, and had a good repeatability and veracity.
