Bột PMMA pha tạp với aluminat tạo ra từ phương pháp một bước thuận lợi để loại bỏ ion đồng từ dung dịch nước
Tóm tắt
Một loại vật liệu nano compozit polymethyl methacrylate/boehmite mới với hiệu suất hấp phụ Cu(II) được tăng cường một cách đáng kể đã được tổng hợp từ $${\text{Al}}({\text{NO}}_{3} )_{3} \cdot 9{\text{H}}_{2} {\text{O}}$$ bằng phương pháp sol-gel đơn giản. Nghiên cứu đã khám phá ảnh hưởng của hàm lượng boehmite, thời gian tiếp xúc và hình thái của hợp kim (pH của quá trình tổng hợp) như là các yếu tố chính đối với hiệu suất loại bỏ và khả năng hấp phụ của hợp kim đối với ion đồng. Các hợp chất có hàm lượng boehmite từ 0.7 đến 5wt% và những hợp chất có hình thái khác nhau được chuẩn bị với các giá trị pH khác nhau cho thấy hành vi hấp phụ khác nhau. Các thí nghiệm hấp phụ theo mẻ cho thấy hiệu suất hấp phụ của các hợp kim được cải thiện khi tăng hàm lượng boehmite và thời gian tiếp xúc. Hiệu suất loại bỏ và khả năng hấp phụ cao nhất đạt được khi hợp kim được chuẩn bị ở pH 8 với hoạt tính xúc tác gia tăng đi kèm.
