The present review compiles the work done over the last few decades on the use of lignin
and lignin-based chars and activated carbons as adsorbents for the removal of substances …

Industrial, agricultural, and domestic activities of humans have affected the environmental
system, resulting in drastic problems such as global warming and the generation of …

… raw P. oceanica had higher sorption value than cellulose for Pb, however, yellow 44 sorption
on extracted cellulose was found to be more than on raw P. … It was observed that for raw P. …

This paper describes the conventional and microwave-assisted pyrolysis of coffee hulls at
500, 800 and 1000C. The influence of the pyrolysis method and temperature on the product …

In this work the use of coffee endocarp as precursor for the production of activated carbons
by steam and CO 2 was studied. Activation by both methods produces activated carbons with …

Thermal treatment of activated carbon fibres (ACF) has been carried out using a microwave
device, instead of a conventional furnace. The results show that microwave treatment affects …

… estimate of this number for each sample from the ratio N p =L c /d 002 . The values obtained,
… As already mentioned, the L c values are lower than the true crystallite heights, and the N p …

… at the lower p/p 0 region, Fig. 4 shows the benzene adsorption isotherms, expressing the
relative pressure p/p 0 in a … With regard to benzene adsorption in the low pressure region (p/p 0 …

The production of activated carbons from almond shell, using physical activation by CO 2 is
reported in this work. The used method has produced activated carbons with apparent BET …

… 4 reveals that whereas Spheron6, Sooty Silica and Elftex120 all give nearly linear DR
plots over a wide range of low p/p”, Graphon and Sterling FI give DR plots of quite different …
