Sodium Acetate is a versatile organic compound that manifests as a white crystalline powder or colorless crystals, acclaimed for its high solubility in water, forming a mildly alkaline solution (pH 8-9). Renowned for its strong hygroscopic nature, it mandates airtight storage to avert moisture absorption. In the realm of wastewater treatment, sodium acetate emerges as an exceptional carbon source supplement, swiftly supplying electron donors to denitrifying bacteria, thereby significantly enhancing nitrogen removal efficiency by 40%-60%. This, in turn, bolsters biological phosphorus removal, achieving a noteworthy TP removal rate of over 85%, making it an optimal choice for municipal and industrial wastewater systems characterized by low carbon-to-nitrogen ratios (C/N < 3). In chemical applications, sodium acetate excels as a pH buffer, while its trihydrate form (CH3COONa·3H2O) finds use in heat packs due to its exothermic crystallization properties. Within healthcare, it is indispensable in regulating electrolyte balance and pH in dialysis solutions, and serves as a crucial intermediate or excipient in pharmaceutical synthesis. Produced through the neutralization of acetic acid and sodium hydroxide (CH3COOH + NaOH → CH3COONa + H2O) or as a byproduct in industrial processes, sodium acetate is characterized by its low toxicity, though it may cause mild irritation to the eyes and skin, necessitating protective gear during handling. This biodegradable compound, stored sealed in a cool, dry environment to prevent moisture and heat exposure, offers an economical, practical, and environmentally friendly multifunctional solution catering to diverse industrial, food, medical, and environmental applications.
