Optimization of a methylation procedure to obtain chloroform-soluble humic acids

It will be important in future analyses of humic acids (HAs) by various chromatographic and spectrometric methods to obtain high yields of methylated HAs. A derivatization procedure for permethylation of HAs was evaluated in relation to the yield of the chloroform-soluble fraction. The procedure inv...
