This work evaluated the possibility of lead (Pb), cadmium (Cd) and copper (Cu) ions synergic scavenging by a chloro-phosphate impregnated biochar (CPBC) from aqueous solution. Adsorption experiments displayed that the adsorption capacity of heavy metals by CPBC can be improved better compared with the pristine biochar (BC). The X-ray diffraction (XRD) analysis further demonstrated that the precipitation of Pb(PO)Cl, Cd(PO)Cl and Cu(PO) might be responsible for Pb, Cd and Cu scavenging. The competitive adsorption exhibited that Pb, Cd and Cu would compete for the same adsorption sites of CPBC when they coexisted and the adsorption affinity of CPBC was observed in the following order: Pb > Cd > Cu. The available phosphorus results suggested that the combination of biochar with phosphate materials can both improve the adsorption performance and reduce the risk of eutrophication by using phosphate materials which can provide a promising application for multiple heavy metals scavenging.

To improve the adsorption efficiency, a HPO-modified biochar (CFCP) was prepared using chicken feather and applied to Cd and Pb adsorption. The pseudo-second-order model could explain the Cd and Pb ad...
CaO-biochar composites were prepared by mixed ball milling and pyrolysis of agricultural wastes eggshell and rice straw. The resulting CaO-biochar composites (E-C) showed excellent performance for pho...
This work is the first report of the ability of biochar-immobilized cadmium-resistant bacteria (CRB) on promoting the efficiency of cadmium phytoextraction by Chlorophytum laxum R.Br. The survival of ...
A novel MgO-modified magnetic biochar (MgO@MBC) was made by chemical co-precipitation of Mg/Fe on anaerobic digestion residue (ADR) and subsequently pyrolyzing at different temperatures. MgO@MBC was u...
A novel FeSiCa rich material (IS), chicken manure (CM) and its biochar were investigated for their efficiency in simultaneous remediation of Cd and As uptake by the vegetable Brassica chinensis L. Wet...
The goal of this clinical research study is to find the highest safe dose of the drug 8-chloro-adenosine that can be given in the treatment of chronic lymphocytic leukemia (CLL). Another ...
The brown meat from crab may contain high levels of the heavy metal cadmium. Cadmium is found in the environment and long-term exposure can cause accumulation in the body. High cadmium lev...
Phosphate is present in many of the foods that the investigators eat and is required by many cellular processes. The kidneys are the only organ that excrete the extra phosphate from the di...
This is a prospective Infection Control study comparing rates of antibiotic usage and infections in the General Intensive Care Unit (GICU) in beds with copper impregnated linens versus reg...
The purpose of this study is to compare the use of chlorhexidine-gel-impregnated dressing and the transparent polyurethane film dressing as coverage of the site of insertion of central ven...
An element with atomic symbol Cd, atomic number 48, and atomic weight 114. It is a metal and ingestion will lead to CADMIUM POISONING.
Unstable isotopes of cadmium that decay or disintegrate emitting radiation. Cd atoms with atomic weights 103-105, 107, 109, 115, and 117-119 are radioactive cadmium isotopes.
Inorganic compounds that contain cadmium as an integral part of the molecule.
3-Chloro-4-(3-chloro-2-nitrophenyl)pyrrole. Antifungal antibiotic isolated from Pseudomonas pyrrocinia. It is effective mainly against Trichophyton, Microsporium, Epidermophyton, and Penicillium.
A method which uses specific precipitation reactions to separate or collect substances from a solution.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
