| Abstract: | The enhancement effect of water-soluble polymers for laser thermal lensing spec troscopy(TLS) has been investigated. It is shown that the thermal characteristics and mi croenvironment of determination system are changed, when the water-soluble polymers are added into the system. The sensitivity of TLS analysis and the stability of the color system are enhanced. The method has been used to determine trace iodine and water soluble phos phorus in soil with satis factory results in the presence of water-soluble polymers. |
