TLDR
In this article, chitosan-modified biochars were synthesized in efforts to produce a low-cost adsorbent for heavy metal environmental remediation, and the results showed that the coating of chitosa on biochar surfaces could improve its performance as a soil amendment or an adorbent.About:

Urea formaldehyde modified alginate beads with improved stability and enhanced removal of Pb2+, Cd2+, and Cu2.
TL;DR: Characterization results showed that UF modification enhanced the pore network and structural stability of the beads, which can be attributed to the reduced intermolecular forces and plentiful of nitrogen and oxygen donor atoms of the bead.

The Current Scenario and Prospects of Immobilization Remediation Technique for the Management of Heavy Metals Contaminated Soils
Hafiz Muhammad Tauqeer,Maryam Fatima,Audil Rashid,Ali Khan Shahbaz,Pia Muhammad Adnan Ramzani,Muniba Farhad,Zeeshan Basharat,Veysel Turan,Muhammad Iqbal +8 more
TL;DR: In situ immobilization of heavy metals through organic, inorganic, and other stabilizing additives seems to be the most promising remediation technique in managing HMs pollution as mentioned in this paper. But, weathering activities may increase the risk of HMs remobilization due to the breakdown of organic amendments.

A review of biochar and its use and function in soil
TL;DR: The potential to sequester carbon as thermally stabilized (charred) biomass using existing organic resource is estimated to be at least 1 Gt/yr − 1 and biochar, defined by its useful application to soil, is expected to provide a benefit from enduring physical and chemical properties.

Positive and negative carbon mineralization priming effects among a variety of biochar-amended soils.
TL;DR: In an effort to better understand the interaction of pyrogenic C and soil organic matter (OM), a range of Florida soils were incubated with a variety of laboratory-produced biochars and CO 2 evolution was measured over more than one year as discussed by the authors.
