Title: **Tetsuya Watanabe: Innovator in Nitrogen Oxide Removal Technologies**

Introduction

Tetsuya Watanabe, an accomplished inventor based in Iwaki, Japan, has made significant contributions to the field of environmental technology. With a total of six patents to his name, he has focused primarily on efficient methods for removing nitrogen oxides from gases, a pressing environmental concern.

Latest Patents

Watanabe's latest innovations include an absorbing solution for the removal of nitrogen oxides from gas. This solution is notable for its ability to efficiently eliminate oxides of nitrogen by contacting the gas with an aqueous solution that contains an organic acid alkali salt and a metal salt from a selected group including Fe, Co, Ni, Cu, and Mn, along with a sulfurous acid alkali salt. The use of polybasic acid alkalis, such as ethylenediamine tetracarboxylic acid alkali salt or nitrilo-tricarboxylic acid alkali salt, enhances the removal efficiency.

In addition, he developed a method for converting nitrogen oxides from gas into a salt of imidodisulfonic acid. In this method, the gas containing nitrogen oxides is absorbed in an aqueous solution that includes at least one ferrous salt and one sulfurous acid alkali salt, allowing for effective nitrogen oxide reduction.
