Abstract Graphite furnace atomic absorption spectroscopy has been used to develop a quick and accurate test for tire cord dip pick up. Strontium nitrate solution is added to either predips or resorcinol-formaldehyde latex dips at predetermined levels of a few parts per million. Sufficient replicate analyses of one to three milligram samples of treated cord can be run to provide reliable data on both the absolute level of dip pick up and the short term uniformity of the dip. The technique offers substantial advantages in both turn-around time and total analysis time relative to wet gravimetric techniques in current use.

Cymbopogon citratus(DC.) Stapf commonly known as lemon grass is used extensively as green tea and even as herbal tea ingredient across the world. Plants have the ability to uptake metals as nutrient from the soil and its environment which are so essential for their physiological and biochemical growth. Concentrations of these twelve trace elements, namely, Mg, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Mo, As, Cd, and Pb, are analysed by graphite furnace-atomic absorption spectroscopy (GF-AAS) and are compared with the permissible limits of FAO/WHO, ICMR, and NIH, USA, which are found to be within permissible limits. Toxic metals like As, Cd, and Pb, analysed are within the tolerable daily diet limit and at low concentration.
