The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The current study investigated the removal of toxic metals namely chromium (Cr), nickel (Ni), and zinc (Zn) from aqueous solutions in batch and column studies using biochar produced by the marine algae Ulva reticulata. SEM/ EDX, FTIR, and XRD were used […]

Utilizing organic waste to sustain agricultural productivity poses a global challenge. Increasing soil organic carbon through compost-biochar pellets emerges as a promising strategy for sustainable agricultural productivity. Therefore, the objective of this study was to produce soil amendment pellets (SAPs) using various mixtures of compost (cow dung, Albizia saman leaves, Dipterocarpus alatus leaves, and mixed […]

Efficient sorbents that have high sorption capacity and suitable separability are promising and are urgently needed to remove diverse contaminants from water environments. In this study, nitrogen-doped magnetic porous biochars (NMPBs) were synthesized from marine algae by a three-step process consisting of prepyrolysis, copyrolysis and coprecipitation. For NMPBs, the surface area was up to 1531 […]

Nanoscale zero-valent iron (nZVI) was cured by vulcanization and biochar functionalization to overcome the tendency of oxidation and aggregation, and the sulfurized nano-zero-valent iron functional material supported by amino biochar (SnZVI-BC-NH2) was obtained, which was used to remove U(VI) from wastewater in this study. A variety of measurements (SEM, TEM, XRD, BET, VSM, FT-IR, and […]

Biochar (BC) and humic acid (HA) are well-documented in metal/metalloid detoxification, but their regulatory role in conferring plant oxidative stress under arsenic (As) stress is poorly understood. Therefore, we aimed at investigating the role of BC and HA (0.2 and 0.4 g kg(-1) soil) in the detoxification of As (0.25 mM sodium arsenate) toxicity in […]

Chemical fertilizers are the primary source of crop nutrition; however, their increasing rate of application has created environmental hazards, such as heavy metal toxicity and eutrophication. The synchronized use of chemical fertilizers and eco-friendly biological tools, such as microorganisms and biochar, may provide an efficient foundation to promote sustainable agriculture. Therefore, the current study aimed […]

Research on synthesizing efficient composites and their application on chlorophenol-contaminated site remediation is needed. This research explored the iron and nitrogen co-doped biochars (Fe-N@BCs) for removing 2,4,6-trichlorophenol (TCP) from an aqueous solution. Specifically, Fe-N@BCs synthesized by co-pyrolysis of the mixture of iron (FeCl3), nitrogen (melamine and chitosan), and carbon (wood sawdust) at temperatures from 300 […]

This study investigated the efficacy of organic soil amendments: bokashi (Bok), biochar (BC), and their combination (Bok_BC) in promoting soil health, nutrient availability, and growth of Carrizo citrange (X Citroncirus sp. Rutaceae, Parentage Citrus sinensis x Poncirus trifoliata) under indoor greenhouse settings. Results indicate significant alterations in soil parameters like total carbon (C), total nitrogen […]

This work examines the synthesis of a novel calcium rich biochar (MB -900) and its application for phosphorus (P) and amoxicillin removal from synthetic and treated urban wastewaters under static and dynamic conditions (laboratory column and continuous stirring tank reactors (CSTRs)). Characterization techniques show that MB900 has an enhanced structural, textural and surface chemical properties. […]

The present work demonstrates a novel strategy of synthesizing iron-biochar (Fe@BCSB) composite made with the waste iron bottle cap and sugar cane bagasse for implementation in the three-dimensional electro-Fenton (3DEF) process. The catalytic ability of the Fe@BCSB composite was explored to remediate the sodium dodecyl sulphate (SDS) surfactant from wastewater at neutral pH. At the […]
