Evaluation of the copper(II) complexing ability of ultrafiltered humic acid by the solvent extraction method.
A commercial humic acid dissolved in water was fractionated to nine samples by means of ultrafiltration (UF); the nominal molecular weight used for UF membranes was 1 k-200 kDa. Concerning the nine samples, copper(II) complexing capacities (CuCC) and conditional stability constants (beta) of the formed copper(II) complexes were measured by a solvent extraction method. A total organic carbon (TO...
متن کاملHow valid is the tallquist method in screening pregnant women with anemia in poor rural settings of southwestern Nigeria?
Background: Diagnosis of anemia is challenging in resource-poor settings due to inadequate laboratory resources. This study assessed the validity of the Tallquist haemoglobinometer in assessing anemia among pregnant women in Osogbo, Southwestern Nigeria. Methods: This was a cross - sectional study, in which 200 pregnant women of reproductive age were selected using multist...
متن کاملStudying the Efficiency of XAD-7HP Anionic Resin in the Extraction of Humic Acid from Surface Water
Introduction: Humic substances (HSs) are very complex and heterogeneous organic matter with high molecular weight and various functional groups, which are produced from the chemical and biological degradation of plants and animal tissues. HS can cause: colour, odour and taste problems in drinking water, biological growth in distribution systems, increase in chlorine demand for disinfection, mem...
متن کاملThe Basic Humic Acid Products
Over at least twelve years of actual field experience with an ample variety of humic acid formulations (some of them developed many years before) have given us a singular degree of expertise in Latin America and a few other markets. Among other things, we have learned to distinguish between humic acids of high biological value, and humic substances of little biological activity. We have found c...
متن کاملHumic acid protein complexation
Interactions of purified Aldrich humic acid (PAHA) with lysozyme (LSZ) are investigated. In solution LSZ is moderately positively and PAHA negatively charged at the investigated pH values. The proton binding of PAHA and of LSZ is determined by potentiometric proton titrations at various KCl concentrations. It is also measured for two mixtures of PAHA–LSZ and compared with theoretically calculat...
