This report deals with atomizing effect of carbon black for the direct determination of aluminum silicate by graphite furnace atomic absorption spectrometry, and aluminum in andalusite was determined with this practical method.
It has been observed that the aluminum absorbance was increased about 1.4 times by addition of 1 w/v% carbon black in aluminum silicate and the sensitivity of aluminum silicate with 1 wfv% carbon black addition was 0.54 ng/1% abs.
The analytical results of aluminum in andalusite determined with this method was 44.2 %as aluminum oxide.
