摘要:

A method for washing charcoal to remove phosphorus contamination prior to decolorisation of soil extracts is reported. Washing with 6M HCl in a column was more effective than washing with the extractant solution. Leaching of the charcoal in a column allowed a more uniform washing and was less demanding of operator time than shaking and leaching through a Buchner funnel.
