A simple method for quantifying the humic content of commercial products

Technical Note


A method based on an analytical technique, initially developed for quantifying aquatic refractory organic matter (often called humics), has been applied to commercial samples claiming to contain humic-type substances. At present, no method exists for quantifying the humic content on this type of sample. The analytical method is based on measuring the peak current obtained by adsorptive stripping voltammetry of the complex formed by refractory organic matter in the presence of trace amounts of Mo(VI). The quantification procedure requires the response obtained for the unknown sample to be compared with the response obtained with International Humic Substance Society (IHSS) reference humic substances. A very simple procedure that enables the humic content of any sample to be expressed as IHSS standard equivalents is described in detail. The method is highly selective, reproducible and suitable for routine analysis.

We would like to thank Humintech (Düsseldorf, Germany) for kindly providing us with a sample of Humiron (WSG-6) and Juan Carlos Rodríguez-Murillo (CSIC, Spain) for helping us to obtain some of the commercial samples.
