Taking mannitol as a masking agent for titanium and chrome azurol S as chromogenic agent, aluminum contents are measured in titanium alloy. This method needn’t eliminate interference by precipitation separation just as in the traditional analysis which is simple in analysis procedure, short in analysis time and accurate in determining results.
