One-grams of a sediment sample was digested with 5 ml conc. HCI followed by 3 mi HNO, and then by 5 ml conc. HF and heated to dryness, then added 10 ml d- jonized water. The sample solution filtrated into 100 ml V-flask and diluted to the mark with 1% HNO3. For quantitative analysis standards, solutions were papered and measured by flame photometer for their emission, as shown in the table below. 10.
