KJELDAHLIZATION Meaning and
Definition
-
The term "Kjeldahlization" refers to a highly important method in analytical chemistry used to determine the nitrogen content in organic and inorganic compounds. This technique is named after Johan Kjeldahl, a Danish chemist who developed the method in the late 19th century. Kjeldahlization is widely recognized as a reliable and versatile procedure for nitrogen determination, particularly in the field of food analysis.
The process involves several steps. First, the sample is digested with concentrated sulfuric acid, which completely oxidizes organic nitrogen into its ammonium form. The resulting solution is then heated gently, causing the ammonium ions to react with an alkaline solution, typically sodium hydroxide. This reaction effectively converts the ammonium ions into ammonia gas.
The liberated ammonia is then transferred into a receiving solution, containing a known amount of acid, where it undergoes reaction with the acid. The excess acid is subsequently titrated with a standardized solution of a base, typically hydrochloric acid, until a neutral endpoint is achieved. The quantity of base solution required to achieve neutrality directly relates to the amount of ammonia in the original sample, and thus, the nitrogen content.
Kjeldahlization is widely utilized in diverse industries, including agriculture, environmental monitoring, and food production. It enables accurate measurement of nitrogen levels, which can be used as an indicator of protein content in food analysis or as an essential parameter in the assessment of water quality. The method's reproducibility, precision, and versatility have made it an indispensable tool in laboratories worldwide.

Etymology of KJELDAHLIZATION
The word "Kjeldahlization" is named after Johan Kjeldahl, a Danish chemist who introduced the method it represents. Johan Kjeldahl developed a technique for determining the amount of nitrogen in organic substances through a process called nitrogen estimation or determination. This method is widely used in various fields, including food analysis, agriculture, and environmental sciences. Hence, the word "Kjeldahlization" is derived from Johan Kjeldahl's surname.
