Abstract
A method for purifying blood plasma by treating said blood plasma with powdery or granular active carbon whereby the purification is carried out continuously by leading the blood plasma, having a pH of 2-5, through a column filled with active carbon, whereby the particle size of said active carbon substantially ranges from 50-500 .mu.m.
Claims8
A method for purifying blood plasma employing the steps of obtaining a supply of blood plasma, pretreating the blood plasma supply to establish a blood pH level ranging from 2-5, passing the supply of pretreated blood plasma through a column filled with active carbon in which the particle size of the active carbon ranges from about 50 to about 500 .mu.m, collecting purified blood plasma, periodically stopping the passing of the supply of blood plasma through the column and regenerating the active carbon column by successively washing the active carbon with an alkaline solution at a temperature of 45.degree.-50.degree. C. and then treating the column with an acid solution to bring the pH of the active carbon to at least neutral.
