Biochar Adsorption Reference Database

 

[ Last updated: Saturday, December 31, 2016 ]

 

 

Preamble

 

The volume of research on the topic of biochar has grown by leaps and bounds in recent years.

 

A Web of Science search for articles, reviews, books, abstracts, data studies, and reports including the keyword “biochar” reveals that the number of studies published per year has grown from a handful in the mid-2000s to over 900 in 2015.

 

Web of Science results for keyword “biochar,” inclusive of articles, reviews, books, abstracts, meeting abstracts, data studies, corrections, data sets, and reports, and excluding patents, letters, news, editorial material, “unspecified,” and “other.”

 

 

An emerging subset of biochar research pertains to its application as an environmentally sustainable and cost-effective adsorbent. In recent years an increasing number of studies have quantified different biochars’ capacity for uptake of nutrients such as ammonium, nitrate, and phosphate, greenhouse gases, heavy metals, and organic compounds.

 

Our work is primarily concerned with biochar adsorption of organic contaminants from aqueous solutions in the context of water and wastewater treatment. Since we began this work in 2006, studies published on the topic of organic compound adsorption by biochars have grown in proportion with overall biochar research.

 

Studies of organic compound adsorption by biochars published per year as cataloged in our bibliography.

 

 

The potential for use of chars as adsorbents in water contaminant management and environmental remediation has recently been reviewed by several research groups [1-17].

 

As a free, open-access resource for the biochar research/implementation and low-cost water and wastewater treatment sectors, we are pleased to publish our bibliographic reference database online here at Aqueous Solutions.

 

Below you will find a periodically updated bibliography of peer-reviewed studies quantifying organic compound sorption by biochars, broken down into the subcategories “pesticides,” “industrial compounds,” “pharmaceuticals,” and “natural compounds.”

 

First, a word on what is not included in the database:

 

  • Studies of sorption of nutrients such as ammonium, nitrate and phosphate are not included here. Nor are studies of greenhouse gases or inorganic contaminants such as cyanide, arsenic, and heavy metals included. These are, nonetheless, important topics that well deserve the growing concern they are receiving in the biochar research community. We would applaud efforts to generate similar open-access bibliographic reference databases for studies of biochar adsorption of these compounds; here we restrict our focus to organic compounds.

 

  • Studies that have quantified biochar adsorption of organic compounds in soil mixtures are not included here. Likewise this is an important topic and highly relevant approach in biochar adsorption research. However our efforts are focused specifically on biochar adsorption of contaminants from aqueous solutions in engineered systems. Therefore, the studies of greatest utility for our applications directly quantify contaminant uptake under appropriately related experimental conditions. So, for example, we have not included studies of sorption inferred through proxy measures such as plant or insect bioassays.

 

  • Studies using exotic, extensively modified, or otherwise “high-tech” biochars – for example, biochar-nanomaterial composites, physically or chemically activated chars, products of hydrothermal or microwave carbonization, etc., are partially represented in the database but are de-emphasized. The rationale is that we are most interested in “low-tech” chars that can be produced from simple and low-cost technologies, and that are not subsequently altered using techniques that are sophisticated, costly, environmentally hazardous, resource intensive, or otherwise infeasible in developing communities. Rajapaksha and co-workers have provided a recent review of modified “designer” biochar sorbents [17].

 

  • Studies that are only available in non-English languages.

 

Please feel free to contact us with suggestions for improving the database, or if you know of studies that are overlooked here. The database will be updated on an approximately monthly basis.
