Toxicity of acid mine pit lake water remediated with limestone and phosphorus.

17 Sep 2009 Pit lakes are increasingly common worldwide and have potential to provide many benefits. However, lake water toxicity may require remediation before beneficial end uses can be realised. Three treatments to remediate AMD (pH approximately 4.8) pit ... Read more...

Acid sulfate soils and human health--a Millennium Ecosystem Assessment.

Aug 2009 Acid sulfate soils have been described as the "nastiest soils on earth" because of their strong acidity, increased mobility of potentially toxic elements and limited bioavailability of nutrients. They only cover a small area of the world's total ... Read more...

Comparison between monolithic and particle-packed platinum C18 columns in HPLC determination of acidic and basic test mixtures.

30 Jul 2009 Herein we report the results of a comparative study on the performance of Monolithic RP-18e and Platinum C(18) 3 mum columns for isocratic separation of acidic and basic test compounds. The inter- and intraday precision of different practical ... Read more...

Technical information about 'Acids'

Definition: Chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. (Grant & Hackh's Chemical Dictionary, 5th ed)
