THE TORSIONAL VIBRATIONS OF THE AMMONIUM IONS IN AMMONIUM IODIDE AND AMMONIUM BROMIDE [PDF]

Chemistry Letters, 1973
Abstract The far-infrared spectra of NH4I and NH4Br have been measured at temperatures of −223 to −53 °C. The torsional vibrations of the NH4+ ions in the phase III crystalline salts were observed at 301 cm−1 for NH4I at −223 °C and at 348 cm−1 for NH4Br at −166 °C.

Nessler Method Verification for Determining Ammonia in Shrimp Pond Wastewater and Its Application in the Ammonia Adsorption Test with Lampung Natural Zeolite

Alchemy
Ammonia levels exceeding 0.50 mg/L can threaten organisms in aquatic environments. The Nessler method is one of the ammonia analysis methods based on the reaction between ammonia in a basic solution and Nessler reagent (K2HgI4), forming a colloidal ...
