Tóm tắt

Tóm tắtẢnh hưởng của pH nước và hàm lượng hoạt chất bề mặt cation lên các tính chất bề mặt và độ ổn định của nhũ tương bitum trong nước của Algeria đã được nghiên cứu. Trong khi độ ổn định được định lượng bằng cả phương pháp kiểm tra trong chai và các phép đo phân bố kích thước, các tính chất bề mặt của giao diện nước-bitum được đánh giá thông qua các phép đo sức căng bề mặt. Kính hiển vi quang học cũng được sử dụng để quan sát các giọt nước phân tán trong pha dầu. Kết quả cho thấy rằng việc thêm hoạt chất bề mặt cation với nồng độ 25 mmol L
