Tóm tắt

Trong nghiên cứu này, một vật liệu gel xốp dựa trên polyvinyl alcohol đã được chuẩn bị thành công để loại bỏ ô nhiễm uranium trên bề mặt thép không gỉ. Vật liệu đã được thử nghiệm thông qua phổ hồng ngoại và phân tích nhiệt trọng lượng. Quá trình làm sạch chất ô nhiễm của gel xốp trên bề mặt thép không gỉ đã được phân tích bằng SEM/EDS và XPS. Kết quả cho thấy gel xốp có tính chất tẩy rửa tốt, và hệ số loại bỏ ô nhiễm uranium phóng xạ trên bề mặt thép không gỉ có thể đạt tới 90,9, có vẻ tốt hơn so với các phương pháp rửa bằng nước và lau chùi.
