Tóm tắt
Trong nghiên cứu này, vật liệu silica gel mang chất lỏng ion 3-alkyl-1-vinyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (XT1 và XT2) và 1,8-diazabicyclo[5.4.0]undec-7-enium bis((trifluoromethyl)sulfonyl)amide (XT3) được tổng hợp thành công và xác định cấu trúc bằng các phương pháp FT-IR, TGA, EDX và BET. Sau các thí nghiệm khảo sát, vật liệu SiO2-XT3 cho hiệu suất thu hồi tốt đối với 5 ion kim loại nặng là Cr3+, Ni2+, Mn2+, Cu2+ và Cd2+ với hiệu suất thu hồi trong khoảng từ 79-104% ở pH 8,5 với 1 mL dung môi rửa giải HNO3/H2O 1 M. Trong điều kiện đã tối ưu, phương pháp này có thể phân tích ion kim loại nặng với LOQ từ 1,95-4,27 µg/L đối với nước máy độ lặp lại tốt (RSD <6%), đạt theo tiêu chuẩn AOAC.
