A possible replacement of previously recommended Spheron-Thiol resin gel for measuring mercury by diffusive gradients in a thin film (DGT) was studied. Duolite GT73 resin and newly prepared 6-mercaptopurine modified Iontosorb AV as binding phases were tested. The preparation procedure of resin-embedded gels was optimized and DGT with new resin gels verified. The verified DGT containing new resin gels was used for in situ mercury measurement in Svitava River.
