Summary, etc. <p style="text-align: justify;">Mellitic acid sensitized luminescence of Tb<sup>3+ </sup>in methanol exhibits a strong emission which is about 500 times more intense than that observed in water. Under optimal conditions, the luminescence intensity exhibits an excellent linear relationship in the concentration range of 5 × 10<sup>-10</sup>–5 × 10<sup>-8</sup> <em>M</em> with a detection limit of 3 × 10<sup>-11 </sup><em>M</em>. The interferences due to other lanthanides have been examined and found to be tolerated up to about 100-fold excess<sup> </sup>and hence estimation of Tb<sup>3+ </sup>in the presence of excess of lanthanides is possible. This method has been applied to the estimation of Tb<sup>3+ </sup>in simulated rare earth and tap water samples and the result is comparable to the result obtained from ICP-MS. Mechanism of enhanced luminescence is also proposed. This is the first report where mellitic acid sensitized luminescence is applied for the estimation of Tb<sup>3+</sup>.</p><p style="text-align: justify;"> </p>
