New technologies are in development regarding the preservation of waterlogged archaeological wood items contaminated with Fe/S species. To this purpose, a biobased treatment to extract these harmful species before further damages occur is presented. Thiobacillus denitrificans and desferoxamine were employed based on their specific properties to solubilize iron sulfides and uptake iron.

Copper, iron, iron III, chromium III, chromium VI, lead, and nickel all interfere at ion extraction above 0.05 μg L 1 while silver and cobalt II interference occurs at concentrations greater than 0.150 μg L 1. Yoshimura et al. 891 described an ion exchanger colorimetric method for the determination of zinc.

The iron is then drained from the bottom of the furnace into a mould and allowed to harden. 16 The blast furnace remains the principal method of smelting iron to this day. 14 There is a tradeoff for this speed, however melting the iron causes it to take on a very high (24%) carbon content, thus resulting in brittle cast iron .

Extraction methods of iron and aluminium Extracting iron from iron ore using a blast furnace Iron is extracted from iron ore using carbon and limestone inside a blast furnace. Iron ores are present as iron oxides in rocks like magnetite and haematite. These are mined from the ground in massive open cast mines in the USA, Canada, Brazil, Australia,

EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.

Cast iron is made when pig iron is remelted in small cupola furnaces (similar to the blast furnace in design and operation) and poured into ms to make castings. It usually contains 2% to 6% carbon. Scrap iron or steel is often added to vary the composition. Cast iron is used extensively to make machine parts, engine cylinder blocks, stoves
