Lead accumulation in soils is of serious concern in agricultural production due to the harmful
effects on soil microflora, crop growth and food safety. In soil, speciation of lead greatly …

The widely existed humic acid (HA) with abundant redox-active groups has been considered
to play an important role in biogeochemistry in sediments and soils. Recent studies reported …

Amending Pb-affected soil with biochar (BH) and magnesium potassium phosphate cement
(MKC) reduces Pb uptake in plants. Moreover, foliar applications of melatonin and proline …

This study investigated the effectiveness of sugarcane bagasse biochar (SBB) in reducing
the toxicity of heavy metals (HMs) in Cd-contaminated calcareous clay soil and improving …

Since few researches were conducted regarding adsorption kinetics of lead (Pb) especially
in calcareous soil therefore, this study has been conducted to determine the Pb adsorption …

This research work reports on pure and acid-treated fennel seed biomaterials for the
removal of metal ions of copper Cu (II), lead Pb (II), and methylene blue (MB) dye from …

Today, a variety of techniques are employed to lessen the harmful impacts of soils with high
levels of heavy metals. In this case, using biochar is a fairly recent technique to lessen the …

A novel urea-functionalized magnetic biochar (MBCU) was prepared, characterized and
evaluated for removal of lead (II) from aqueous solution. The results of SEM, BET, XPS …

This paper presents a method of agricultural waste management—the production of two
biochars (BC) from potato and raspberry stems. It defines the potential of these materials for …

Coal bottom ash is one of coal combustion wastes which mainly contains metal oxides of
alumina and silica, thus it can be potentially used as adsorbent for heavy metal removal in …
