Performance Evaluation of Small Sized Powdered Ferric Hydroxide as Arsenic Adsorbent

Granular Ferric Hydroxide for Elimination of Arsenic from Drinking Water

90Y ferric hydroxide colloid.

At the Radiochemical Centre we have recently developed a new 90Y colloid which has greater stability than the currently available 90Y silicate colloid and appears from the results of animal tests to be suitable for the treatment of rheumatoid knee joint effusions. In this report the need for a new 90Y colloid is assessed and the preparation and properties of the new colloid are described. Curre...

Natural attenuation of arsenic by ferric hydroxide in a coastal aquifer

Groundwater in a coastal sand aquifer is enriched in arsenic as a result of historical discharges from an industrial facility on the central NSW coast. Subsequent investigations also identified arsenic in the soil within the saturated zone down-gradient of the source area. Arsenic concentrations in soil and groundwater decrease markedly along a narrow flow path towards a tidal river some 300 m ...

Removal of Alizarin Red Dye Using Calcium Hydroxide as a Low-cost Adsorbent

Calcium ions have very strong affinity and binds effectively to alizarin red dye during staining of biomaterials. This promotes us to choose calcium hydroxide as a low cost adsorbent for the removal of alizarin red dye. Various parameters such as pH, concentration, dose of adsorbent, time, and temperature have been investigated. In addition, enthalpy, entropy, free energy and activation energy ...

Adsorption of arsenic(III) and arsenic(V) from groundwater using natural siderite as the adsorbent.

Batch and column tests were performed utilizing natural siderite to remove As(V) and As(III) from water. One hundred milligrams of siderite was reacted at room temperature for up to 8 days with 50 mL of 1000 microg/L As(V) or As(III) in 0.01 M NaCl. Arsenic concentration decreased exponentially with time, and pseudoequilibrium was attained in 3 days. The estimated adsorption capacities were 520...
