A new class of compounds, called as ionic liquids, has recently emerged as potential substitute for volatile organic solvents. Ionic liquids possess certain special physico-chemical characteristics that render them very useful in different areas of research and development. In this review, the physico-chemical properties and the applications of ionic liquids in chemical processes are critically...
in this research, the physico-chemical water quality parameters and the effect of climate changes onwater quality is evaluated. during the observation period (5 months) physico-chemical parameterssuch as water temperature, turbidity, saturated oxygen, dissolved oxygen, ph, chlorophyll-a, salinity,conductivity, and concentration of total nitrogen (nutrient level) as main pollutant factor have be...
Bioremediation uses various microorganisms to detoxify or degrade various harmful substances in the nature, particularly soil and water. In the proposed work, five species of micro-organisms were used to analyse their impact on various physico-chemical parameters of water. In the first attempt the actual physico chemical parameters of the collected sample water were noted down (Fresh sample par...
Boehmite (γ-AlOOH) nanoparticles (NPs) are used in a wide range of industrial applications. However, little is known about their potential toxicity. This study aimed at a better understanding of the relationship between the physico-chemical properties of these NPs and their in vitro biological activity. After an extensive physico-chemical characterization, the cytotoxicity, pro-inflammatory res...
The aim of our experiment was to determine the effect of heating oil application on the count of microorganisms and some physico-chemical properties of limed and lime-free soil and soil sown with yellow lupine of the Markiz variety and unsown soil. The results obtained indicate that heating oil deteriorated the physico-chemical properties of the experimental soil (acidification, decrease in the...
Life on Earth can be traced back to as far as 3.8 billion years (Ga) ago. The catastrophic meteoritic bombardment ended between 4.2 and 3.9 Ga ago. Therefore, if life emerged, and we know it did, it must have emerged from nothingness in less than 400 million years. The most recent scenarios of Earth accretion predict some very unstable physico-chemical conditions at the surface of Earth, which,...
Fruit pulp of Mangifera indica Linn. is an important Ayurvedic medicine which is useful in gastric disorders, dyspepsia, loss of appetite, urine incontinence, uterine diseases, heat apoplexy, pharyngitis, ulcer, dysentery, sun stroke etc. The present study for the first time attempts to investigate physico-chemical and pharmacognostic properties as per WHO guidelines of this drug. Detailed acco...
This Paper Present to study of the Physico-chemical Parameters of Fateh Sagar Talab in Bagar of Jhunjhunu district in Rajasthan. The study was carried out for a period of one year i.e. July 2012 to June 2013. Water samples were collected monthly from surface water and analyzed for Temp, pH, electric conductivity, total hardness, Alkalinity, TDS (Total dissolved solid), chloride, DO (Dissolved o...
