The effect of SO2-4 concentrations on the performance of anaerobic granular sludge were investigated using batch experiments with the sludge obtained from an operating anaerobic baffled reactor(ABR).

To study on the process of removal of SO2-4 from sodium multi-component solution and add some additive to remove the SO2-4 from the solution.

In the rapid ion-chromatographic determination of PO3-4,SO2-4 and NO-3 anions in the drink "Coca Cola",the combining use of the columns of Dionex IonPac AS14 and IonPac AG14 was substituted by the single used of the IonPac AG14A,as chromatographic column which made the 3 anions separated satisfactorily within 3 min.

In this article,sulfate concentration and sulfur oxidation ratio in heating season were measured with on-line systems,and the relationships between sulfur oxidation ratio and influencing factors were discussed.

The technology of microbial U(VI) reduction by sulfate reducing bacteria(SRB) was employed to treat simulated wastewater from in situ leach(ISL) uranium mining.

After TiO_2 catalyst was regenerated by light in the presence of air,S~0 was converted to SO_4~(2-),the photocatalytic activity of TiO_2 was recovered.

Object: To establish a method for the simultaneous determination of Cl~-and SO_4~(2-) in nicotinic acid by ion chromatography.

On SO_4~(2-) Adsorption and Desorption Characteristics of Two Red Soils in Hunan Province;

Sulfate reducing bacteria(SRB) are domesticated under the conditions of different pH values and sulfate ion concentrations,and the decontaminating effect of SRB on the groundwater simulating in-situ leach uranium mines is studied.
