Total nitrogen determination
As a preliminary to the consideration of automated, or more correctly mechanized, methods for the determination of total organic nitrogen the discussion of some general aspects of nitrogen determination is illuminating. There are at least four recent reviews, for example those by Bradstreet (1965), Fleck & Munro (I965), Jacobs (1965), and Munro & Fleck (1969), of the determination of nitrogen f...
متن کاملRemediation of total petroleum hydrocarbons using combined in-vessel composting and oxidation by activated persulfate
This study was investigated the efficiency of activated persulfate and in-vessel composting for removal of total petroleum hydrocarbons. Remediation by activated persulfate with ferrous sulfate as pre-treatment was done at batch system. In the chemical oxidation, various variables including persulfate concentrations (10-3000 mg/g as waste), ...
متن کاملDetermination of total nitrogen in aqueous samples using persulfate digestion
Determination of total nitrogen in aqueous samples after potassium persulfate digestion compared favorably in both precision and nitrogen recovery with determinations obtained using Kjeldahl digestion. The determination of total nitrogen (TN = inorganic and organic fixed nitrogen) has largely depended either on acid Kjeldahl digestion ( cf. Strickland and Parsons 1972) or on photo-oxidation (Ar...
متن کاملDetermination of Total Nitrogen and Phosphorus in Wastewaters by Alkaline Persulfate Digestion Followed by IC
Introduction Excess use of nutrients over the last several decades has caused significant water quality and health issues on a global scale. In the U.S., the impact of nutrient pollution has been identified as one of the most widespread, costly, and challenging environmental problems in the 21st century.1 Nutrient pollution causes excess algae growth (i.e., algal blooms) over large bodies of wa...
