Technical data Water quality - contamination by heavy metals with Cobra SMARTsenseArticle no: P0990169 ![]()
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Principle Heavy metal ions can get into surface or ground water from deposits or through the waste water of galvanic or similar production plants. They block the action of enzymes so that the metabolic processes controlled by these enzymes can be disturbed or blocked by organisms. With the help of urea hydrolysis, the blockage of enzymes by heavy metal ions can be measured with conventional laboratory methods. Benefits
Tasks The students investigate two enzymatic cleavage processes, one with and one without the addition of heavy metals. Learning Objectives The students should recognize that heavy metals can influence the effect of enzymes.
