Giant reed was used as precursor for making biochar in order for the adsorption of NH 4+–N
from aqueous solution. And the adsorption of the product to NH 4+–N was examined. The …

Biochar has abundant oxygen-containing functional groups and a unique surface structure,
which endow it with properties that are desirable for various environmental protection …

Nitrate cycling is essential in sustaining soil systems. Excessive application of N-fertilizers
and the associated underground water contamination have attracted a great deal of …

Biochar-based adsorption process, for its environmental and economic benefits, has
recently become a new method of pollution control. Nevertheless, biochar generally has a …

The adsorption treatment of nitrate wastewater has attracted much attention worldwide.
However, most of the currently enhanced adsorption methods used chemical modification …

We converted different biochars from nine common feedstock were prepared for aqueous
NH 4+ adsorption. The biochars were classified into three groups: wood-like (B@ A: wood …

A series of biochars were prepared by pyrolyzing oak sawdust with/without LaCl 3
involvement at temperature of 300–600° C, and approximate and ultimate analyses were …

Ammonium pollution caused by human activities threated to eco-environment and the
groundwater was polluted by rain and other leaching processes. This study investigated the …

The effects of biochar on soil properties including nutrients have been reported in previous
studies, but few studies targeted on soil nitrogen. Moreover, there remains a lack of studies …

Using biochar as an adsorbent is a promising technique for simultaneous recovery of
ammonium and phosphate from wastewater. However, deficiencies in studying the optimal …
