In this study a new electrochemical histamine sensor was proposed by using Ni-based metalorganic framework (Ni-BTC, BTC = 1,3,5-benzenetricarboxylate) crystals and multi-walled carbon nanotubes modified glassy carbon electrode. The modified electrode exhibited excellent electrocatalytic activity for the electro-oxidation of histamine with relatively high sensitivity and stability. The electro-oxidation of histamine was irreversible and exhibited an absorption-controlled behavior. A calibration curve for histamine in the concentration range from 1.00 to 160.00 μM with a detection limit of 0.41 μM (at signal to noise 3) and sensitivity of 0.19 μA μM–1 was obtained. The suggested sensor was successfully used for quantitative determination of histamine in spiked human urine samples with satisfactory results.
