ABSTRACT

Parad (Hg) was procured from market. The mercury obtained was analyzed by XRF and found to have mercury 99.75%. The other impurity was found to be of strontium metal (0.25%). Parad (Hg) contains various metals in different minute proportions and itself is considered as toxic metal in modern chemistry. The ancient seers were aware of these metals in parad which can be toxic to human body. Hence, they have been termed as nagdosha, vangdosha, tamradosha etc. by acharyas. To overcome these doshas, the specific purification measures were advocated in classical texts. In the current study, as per the reference of Rastarangini it is evident that after purification measure the levels of these toxic metals lowered down drastically, which emphasizes an importance of purification according to classics. Mercury was reported to contain copper (Cu), tin (Sn), and lead (Pb) as main impurities. These are toxic metals, particularly copper and lead. In the purification, these two metals need to be removed. On XRF analysis it was found that by the lime treatment strontium (Sr) content in the parad (Hg) was reduced by 25%. In this purification process, there was a loss in weight of parad (Hg) (about 31%). It is observed in XRF analysis that after the purification of parad (Hg) with rason+saidhav, mass of 100% of pure parad (Hg) was obtained. On AAS analysis, it was observed that lead content was reduced up to 1.25mg/lit from 3.31mg/lit. The copper content was also reduced up to
