Competitive biosorption of lead, cadmium, copper, and arsenic ions using algae
The present study aims to evaluate the competitive biosorption of lead, cadmium, copper, and arsenic ions by using native algae. A series of experiments were carried out in a batch reactor to obtain equilibrium data for adsorption of single, binary, ternary, and quaternary metal solutions. The biosorption of these metals is based on ion exchange mechanism accompanied by the release of light met...
متن کاملKinetic Investigation of Myeloperoxidase upon Interaction with Copper, Cadmium, and Lead Ions
Background: Myeloperoxidase (MPO), which is abundantly expressed in neutrophils, catalyzes the formation of a number of reactive oxidant species. However, evidence has emerged that MPO-derived oxidants contribute to tissue damage and initiation and propagation of inflammatory diseases, particularly, cardiovascular diseases. Therefore, studying the regulatory mechanisms of the enzyme activity is...
متن کاملBiosorption of lead, Mercury, and cadmium ions by Aspergillus terreus immobilized in a natural matrix.
Our aim was to investigate the biosorption of Pb2+, Hg2+, Cd2 from aqueous solution by Aspergillus terreus (both free and immobilized on loofa sponge discs). Our results show that the adsorption capacity of fungal biomass on loofa sponge (FBLS) is superior to free fungal biomass (FFB). The adsorption selectivity by FBLS was in the order Pb2+>Hg2+>Cd2+. The maximum metal ions adsorbed was 247.2,...
متن کاملEvaluating the Arsenic, Cadmium, Lead, and Copper levels in certain imported tea samples consumed in Iran
Seven majorly consumed brands of several teas (A1, A2, M1, M2, S, D, and C teas) were selected for the present study. In this study, the heavy metal contents including copper (Cu), cadmium (Cd), arsenic (As), and lead (Pb) were assessed in the black tea samples consumed in Iran. The content of the heavy metals in the samples was analyzed using atomic absorption spectroscopy (AAS). Notably, the ...
متن کاملInvestigation of the Biosorption of Lead (II) from Squeous Solutions using Algae Padina australis
Introduction Lead is one of the most important metal ions that has many disadvantages for the environment and organisms, especially humans. One of the most effective methods for causing lead from aqueous solutions is the use of biological adsorbents. The purpose of this study was to investigate the biological biosorption of lead (II) from aqueous solutions using Padina algae. Materials and Met...
