Báo cáo Nghiên cứu tổng hợp vật liệu bentonit biến tính, ứng dụng hấp phụ phốtpho trong nước

Qua quá trình nghiên cứu điều chế vật liệu bentonite biến tính lantan, hỗn hợp AlLa, AlFe và khảo sát ứng dụng hấp phụ phốtpho trong dung dịch. Chúng tôi rút ra một số kết luận sau: 1. Đã nghiên cứu công nghệ làm giàu bentonit Bình Thuận theo phương pháp CE, với phương pháp này để làm giàu bentonit Bình Thuận cần hoà tan bentonit với nước theo tỷ lệ 1 : 100 (1% huyền phù) để yên trong 24 giờ, tiếp tục khuấy 30 phút, sau đó ly tâm. Sản phẩm thu được có hàm lượng montmorillonit tăng lên khoảng 90%, kết quả được chỉ ra trong hình 3.3 và bảng 3.4. 2. Nghiên cứu điều chế thành công hai vật liệu B90-La và B40-La. Đã khảo sát được ảnh hưởng của các yếu tố: tỉ lệ LaCl3/bentonit, thời gian phản ứng, pH, nhiệt độ và phần trăm huyền phù đến các giá trị khoảng cách cơ bản, d001, từ đó xác định được các điều kiện thực nghiệm thích hợp để điều chế vật liệu bentonit biến tính lantan như sau:
