Removal of Uranium from Mine Water Using Ion Exchange
The water then proceeds to the uranium ion exchange section. The ion exchange configuration is shown in figure 8. There are two lead columns, one in operation and one on standby/regeneration. The aim is to reduce the uranium concentration below 20 碌g/鈩? The lead columns contain 100 鈩?of Lewatit MonoPlus S6368 resin and operate at 20
Uranium carbonate industrial waste streams from a Brazilian nuclear production plant were treated by an ion exchange process using a Type II strong base anion exchange resin, IRA-910A with a dimethyl 2-hydroxy ethyl functional group . The stream needed to be boiled for 6 h to lower the total carbonate concentration before it could be treated.
Uranium Removal by Ion Exchange
uranium levels in the water greater than 30 渭g/L. These systems will need to take measures to reduce the uranium in the drinking water supply. Remedial actions include developing alternate water sources, purchasing water from other providers, or treatment of the water supply. Uranium typically exists in water as the uranyl ion, UO 2 2+, formed

Radium Removal by Ion Exchange. A strong acid cation resin in the sodium form can be used to remove radium from water. Radium has a selectivity coefficient of about 40:1 compared with sodium. This is 8.3 times as high as calcium, which is only 5:1. On a single-use basis, the cation resin will load radium 8.3 times beyond the hardness endpoint.
Uranium elimination and recovery from wastewater with
Uranium concentrations in the wastewater after treatment in the Fe-, Mg-, and Al-EC systems with organic/inorganic chelating ligands are shown in Fig. 1a, b, and c, respectively, and the EC systems without ligands (instant EC) were used as control group. The Fe anode with organic/inorganic ligands clearly improved the uranium removal efficiency.

- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- Who bought polyacrylamide flocculant?
- Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).

- Can acrylamide based flocculants be used in oil sands extraction?
- A representative example comes from the effluents (tailings) of oil sands extraction process that contain high solids organic-contaminated fine clays, where the use of conventional acrylamide-based flocculants does not meet the dewatering criteria needed by this industry. 3
