In the present study, a spectroscopic investigation of Cyperus rotundus using wavelength dispersive X-ray fluorescence (WD-XRF), laser-induced breakdownspectroscopy (LIBS), Fourier-transform infrared spectroscopy and Ultra Violet Visible (UV-Vis) spectroscopy have been performed. The macro and micronutrient minerals detected and quantified in Cyperus rotundus were carbon (C), oxygen (O), sodium (Na), chlorine (Cl), magnesium (Mg), silicon (Si), potassium (K), calcium (Ca), sulfur (S), phosphorous (P), aluminium (Al), iron (Fe), zinc (Zn), manganese (Mn), palladium (Pd), ruthenium (Ru), chromium (Cr), molybdenum (Mo), strontium (Sr), copper (Cu), and nickel (Ni). The minerals detected in Cyperus rotundus using WD-XRF technique was compared with the data obtained from LIBS technique. We have discussed about the medicinal importance of some of the nutrients found in Cyperus rotundus. FTIR spectroscopy has been used to study the molecular composition of Cyperus rotundus. UV-Vis spectroscopy has also been used to study the titled sample to know its molecular composition.

In the present work, spectroscopic investigations have been performed on a kidney stone to determine its chemical composition using Fourier transform infra-red (FTIR) spectroscopy and laser-induced breakdown spectroscopy (LIBS). Fourier transform infra-red (FTIR) spectroscopy were used to classification of stone's type and also to determine its minor constituents. Using FTIR spectroscopy, we have detected calcium oxalate as a major constituent of kidney stone and hence classified as oxalate stone. We have also observed the presence of calcium carbonate in calcite form and calcium phosphate in the kidney stone sample. LIBS has been used to detect the elemental content of kidney stone which were calcium (Ca), silicon (Si), tin (Sn), potassium (K), magnesium (Mg), iron (Fe), copper (Cu), titanium (Ti), fluorine (F), carbon (C), and nitrogen (N). This paper demonstrates FTIR and LIBS as a promising, simple, and accurate analytical method to study kidney stones.
