Efficient degradation of Rhodamine B in water by CoFeO/HO and CoFeO/PMS systems: A comparative study.

In this work, a comparative study of efficient degradation of Rhodamine B (RhB) in CoFeO/HO and CoFeO/PMS systems was performed. Batch experiments indicated that the RhB degradation rate of CoFeO/HO system reached 95.5% at 90 min under the condition of 0.

Use of Eggshell-Catalyzed Biochar Adsorbents for Pb Removal from Aqueous Solution.

Eggshell is a cheap and environmentally friendly calcium source. In this study, Ca-modified biochar adsorbents (CEA) were prepared by 1:10, 1:2, and 1:1 mass ratio of the eggshell and Eupatorium adenophorum. The CEA-2 sample prepared with a 1:2 mass ratio showed a maximum Pb adsorption capacity (97.
