Laser-induced breakdown spectroscopic technique was used to study the elemental profile of beach sand samples of Bangladesh. Apart from Silicon, which is the main elemental constituent of sand, the presence of Li, Na, Mg, Al, Cl, K, Ca, Ti, Cr, Mn, Fe, Zr, Sr, Ba, Te and Zn was identified in the beach sand samples. In addition to the qualitative analyses, quantitative analyses of a particular element Titanium (Ti) has been done. The result shows the presence of (2.98±0.46)% of Ti by weight of the beach sand sample from Himchhori, Chittagong. It was determined by using six calibration curves drawn for six emission lines of TiI (489.991, 498.1732, 499.107, 499.951, 503.591, 506.466 nm) by standard analyte addition method. The limit of detection (LoD) for this six calibration curves varied from 0.14 to 0.3% by weight.
