Obtaining of Activated Carbons by Pyrolysis of Hidrolytic Lignin

Adsorption of lead ions on carbonaceous sorbents of nutshell obtained from secondary raw material

“…In spite of the existence of general theoretical works in each particular instance it is necessary to select specific sorbent [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Therefore, creation of new cheap and effective adsorbents, especially on the basis of waste, is very important.…”

“…Search of new adsorbents in order to solve above mentioned problem in the world is very important. The analysis of literary data [2][3][4][5][6][7][8][9][10][11][12][13][14][15] has shown, that adsorbents, which were used for purification of drinking and wastewaters, oil products and organic solvents are characterized with high cost price and complicated regeneration technologies.…”
