Application:

Analytical procedure for the simultaneous voltammetric determination of trace metals in food and environmental matrices. Critical comparison with atomic absorption spectroscopic measurements.: This paper presents an analytical procedure utilizing ammonium citrate dibasic for the simultaneous voltammetric determination of trace metals in food and environmental samples. The study demonstrates the method′s efficacy compared to traditional atomic absorption spectroscopy (Melucci et al., 2007 ).

Overlapping voltammetric peaks--an analytical procedure for simultaneous determination of trace metals. Application to food and environmental matrices.: The study details an analytical method using ammonium citrate dibasic to resolve overlapping voltammetric peaks, allowing for the simultaneous determination of multiple trace metals in complex matrices. This technique is beneficial for environmental monitoring and food safety assessments (Locatelli, 2005 ).

Correlation of biological value of feed phosphates with their solubility in water, dilute hydrogen chloride, dilute citric acid, and neutral ammonium citrate.: This research investigates the solubility of feed phosphates in various solvents, including ammonium citrate dibasic, to determine their biological value. The findings help optimize animal feed formulations for better nutritional outcomes (Sullivan et al., 1992 ).
