Comparison of different decontamina

Comparison of different decontamination methods
Three methods were used to test the decontamination effect of the uranium contaminated metal surface: coating the uranium contaminated metal surface (D), coating and electrolyzing the contaminated metal surface in solution (E), and coating and electrolyzing the contaminated metal surface in dry medium (F). The three methods are described below.

Method D: Some coating film solution was spread on a piece of stainless steel sample (2.5 cm × 2.5 cm), air-dried, and then the film was peeled off and its properties were measured.
Method E: Some coating film solution was spread on a piece of stainless steel sample (2.5 cm × 2.5 cm), air-dried and electrolyzed. The sample was taken as the anode and another piece of clean metal sample (2.5 cm × 2.5 cm) as the cathode. The electrode distance was 1 cm, electrolysis medium was 0.1 mol/L H3PO4 solution and electrolyzing time was 30 min. After electrolyzing, the sample was picked up and air-dried, the film was peeled off and its properties were measured.
Method F: Some coating film solution was spread on a piece of stainless steel sample (2.5 cm × 2.5 cm), air-dried and electrolyzed. The sample was taken as the anode and another piece of TiO2 mesh (2.5 cm × 2.5 cm) as the cathode. After electrolyzing for 30 min, the film was peeled off and its properties were measured.
