Ultrasonic leaching of bio-collectors for heavy metal analysis
(TAYLOR & FRANCIS LTD, 2000)
A Bio Collector - Ultrasonic Leaching Method (BC-ULM) was developed for the analysis of heavy metals (Pb, Cd,Cr, Ni, Cu, Fe and Al) on plant sprouts for the assessment of environmental pollution. Fabaceae Rabinia Pseudoacacia ...
A simple method for predicting the frequency of the infrared inactive carbonyl stretching mode in LM(CO)(5) molecules with C-4v symmetry
(ELSEVIER SCIENCE BV, 2004)
The paper presents a new method for predicting the frequency of the b(1) mode, which is infrared-inactive, in complexes of the type LM(CO)(5) belonging to C-4V point group. The method was based on the relation lambda(3) = ...
Separation of the protease enzymes of Bacillus licheniformis from the fermentation medium by crossflow ultrafiltration
(JOHN WILEY & SONS LTD, 2000)
The separation from fermentation medium of extracellular serine alkaline protease (SAP) enzyme produced by Bacillus licheniformis was investigated using a crossflow ultrafiltration system. SAP was separated from the high ...
