Asystematic physico-chemical analysis of the groundwater at 41 different locations in Panipat city (Haryana), India has been taken up to evaluate its suitabilityfor domestic purposes. The data revealed considerable variations in the water samples with respect to chemical composition. For the analyzed water samples pH, EC, TDS, TA, TH, Na+, K+, Ca2+, HCO3-, Cl-, SO4(2-) and F(-) varied from 6.6-...

At the turn of the 19th century, Minas Gerais Botanist Friar Veloso worked intensely on the publication of books to promote among settlers from the Portuguese empire techniques for improving agricultural production and from the incipient chemistry industry. This article analyzes the first volume of the "Alographia dos alkalis fixos...", a work that includes articles, book chapters, letters and ...

We have previously observed that the urinary excretion of citrate is reduced to low levels in rats treated with the carbonic anhydrase inhibitor, acetazoleamide (Diamox®g) (1). This first experiment was prompted by the fact that the elevated serum chloride and decreased serum bicar-. bonate concentrations, and the fixation of the urine pH at approximately 7 or above following administration of ...

This preliminary study aims to obtain the lithium compounds from a geothermal brine through solvent extraction. The samples were collected PT Geodipa Energi Geothermal Power Plant in Dieng, Central Java, Indonesia. ICP analysis was conducted measure chemical composition. Brine’s content 62.73 ppm with dominant impurities silica (Si), calcium (Ca), potassium (K), sodium (Na), and boron (B). Sili...

Carbon adsorbents for use in the removal of gaseous toluene from air were prepared buckwheat (Fagopyrum esculentum Moench) hull. A chemically-activated adsorbent was via impregnation raw hull powder with potassium carbonate, followed by thermal decomposition. The exhibited improved adsorption capacity compared to without chemical activation. Toluene concentration decreased 220 ppm 160 during 24...

Abstract The purpose of the work was to analyze first stage UE “Dekhkanabad plant potassium fertilizers” find out reasons for decrease in efficiency process desliming sylvinite ore Tyubegatan deposit. It has been established that is due a content chloride and an increase insoluble residue ore, proportion weakly sludge carbonate sulfate minerals residue, compared with silicate minerals, differen...

In this paper, the preparation of potassium carbonate modified SiO2-Al2O3 composite aerogel, carbonation characteristics K2CO3 and decarburization regeneration cycle were studied. The influence loading rate on CO2 adsorption was studied by using a fixed bed reactor, microstructure samples analyzed combining SEM BET. results show that during alkali fusion sintering Na2CO3, Si-O-Si Si-O-Al bonds ...
