Rapid measuring method of soil cation exchangeable capacity using copper adsorption and spectrophotometer

摘要

The present invention relates to a method for measuring the soil cation substitution capacity using copper adsorption and spectrophotometer, and when dissolved in distilled water naturally compared to the conventional method of causing a water pollution and a complex analysis process using a large amount of reagents By adsorbing a copper solution with a certain concentration of blue to the negative charge of the soil, the concentration of unadsorbed copper is measured by spectrophotometer, so that the cation substitution capacity of the soil can be measured easily, accurately and quickly within a short time. There is a significant cost savings.
