The mobilization of chromium and nickel from an industrial soil was investigated using two biodegradable chelants (citric acid and histidine), compared with a persistent one (ethylenediaminetetraacetic acid). Successive metal mobilizations were carried out in batch experiments. The main reactions involved were estimated by modeling the system with MINEQL+. For a single mobilization, citric acid...
The application of high-resolution analytical techniques to characterize ancient bone proteins requires clean, efficient extraction to obtain high quality data. Here, we evaluated many different protocols from the literature on ostrich cortical bone and moa cortical bone to evaluate their yield and relative purity using the identification of antibody-antigen complexes on enzyme-linked immunosor...
Background and purpose: Zinc (Zn), copper (Cu) and iron (Fe) are essential minerals required for a variety of biomolecules to maintain the normal structure, function, and proliferation of cells. Abnormal metabolism of heavy metals can lead to several chronic pathogenesis. In this study, two new saccharin hydrazide derivatives were synthesized and their chelatory activities were evaluated. Mate...

Abstract During peroxide bleaching of pulp (“P-stage”), the heavy metal ions must be removed from and inactivated by chelation before to prevent undesired degradation cellulose reactive oxygen species. Ethylenediaminetetraacetic acid (EDTA) is mostly used as a chelating agent; however, it may soon banned because environmental concerns. Therefore, there demand for new agents replace EDTA, compre...
