Prediction of principal metal-binding solid phases in estuarine sediments from color image analysis

Article Abstract:

In this study, color image analysis was used to predict the prinicipal metal binding solid phases in estuarine sediments. The article is broken down into an introduction, a discussion of the experiment and a discussion of the results. Various tables and graphs accompany the article.

Selective biosorption of lanthanide (La, Eu, Yb) ions by Pseudomonas aeruginosa

Article Abstract:

Researchers studied the biosorptive properties of Pseudomonas aeruginosa (PA) of heavy metals in a biomass. Investigation centered around PA's ability to remove three trivalent lanthanide ions from wet biomass. Lanthanum, europium, and ytterbium were introduced into test material, subjected to PA, and studied with special interest in pH levels relative to adsorption. Optimum sorption occurred at pH 5.0. The amounts of one metal effected adsorption of another metal. Even so, PA seemed to prefer lanthanum, even while adsorbing the other two metals.
