ranged from 0.01 to 3.37 mg per gram of soil. Literature gives values from 0.1 to 6.5 mg in humicacids and relates the quantity of aliphatic C with degree of soil humification, that decreases as humification increases [ 15 ]. In this article, it is found
centrifugated to separate coagulated humicacids (HA). The non-coagulated fraction with H 2 SO 4 is referred as fulvic acids (FA). The C contents of the THS ( C THS ), HA ( C HA ) and FA ( C FA ) were determined by the Walkley–Black method [ 14

. Mjengera and Mkongo [ 32 ] reported that BC prepared in 400 °C could be used to remove fluoride from water. This sorbent can also be used as a catalyst in ozonation systems for humicacid removal from water [ 33 ].
