Abstract
กรรมวิธีสำหรับแยกส่วนประกอบที่มีสีออกจากตัวทำละลายอนินทรีย์ที่คืนสภาพ ของโพลิแอไครโลไนทริล โดยไม่มีการลดลงของความเข้มข้นที่ประเมินค่าได้ของส่วนประกอบ ที่มีฤทธิ์ ซึ่งใช้เยื่อออสโมซิสแบบย้อนกลับซึ่งมีการคัด NaCl ออกได้ในช่วง 10% ถึง 97% ภายใต้ความดันที่ทำให้เกิดการซึมผ่านที่ต่ำกว่า 20 กก./ซม 2. A process for separating colored components from recovered inorganic solvents. Of polyacrylonitril There was no decrease in the assessed concentration of active components using reverse osmosis membranes where NaCl was eliminated in the range of 10% to 97% under pressure that caused the reverse osmosis. Permeability below 20 kg / cm 2.
