Sulfide

Definition

sulfide ( US ) = SULPHIDE

Examples

1. ‘In this paper
2. we show that the opaline silica and amorphous sulphides are precipitating mainly on filamentous microbes and biofilms
3. which form templates for both the metal-rich sinter and the suspended flocs.’
4. ‘The technique can identify iron-bearing phases (such as oxides
5. silicates
6. sulfides
7. sulfates
8. and carbonates)
9. as well as the amount of iron in each phase and the presence of iron in various oxidation states.’
10. ‘These pollutants include ozone
11. sulphides
12. nitrogen oxides
13. carbon monoxide
14. hydrocarbons
15. and sulphur oxides.’
16. ‘Although an amino acid acceptor of sulphide is necessary for sulphate assimilation
17. only little attention was paid to the regulation of S assimilation by carbon metabolites.’
18. ‘The latter mineral
19. a sulphide of iron
20. has a shiny metallic lustre and was often mistaken for gold itself: it is the infamous fool's gold.’
21. ‘Flasks and bottles full of nitrates and sulphides and chlorates and acetone
22. labelled in English and Arabic
23. lay on dirty tables.’
24. ‘DOCs include all compounds of carbon except for its oxides
25. sulphides and metal carbonates if they are identifiable by chemical name.’
26. ‘Similarly
27. metallic iron and many other metals
28. alloys
29. oxides
30. sulfides and other compounds containing iron and a number of other transition metals can be magnetized.’
31. ‘The solids used include natural clays and minerals
32. metal oxides and sulfides
33. metal salts
34. and mixed metal oxides.’
35. ‘The Podolia ash beds consist largely of clay minerals accompanied by a variety of primary volcanogenic crystals and secondary sulphides
36. sulphates
37. carbonates
38. and silicates.’
39. ‘Most metals are so readily oxidized by atmospheric oxygen that they are only found naturally as oxides
40. sulfides or salts.’
41. ‘By anaerobic bacterial action
42. sulphates are reduced to sulphides and organic material is broken down
43. ultimately to yield carbon dioxide and methane.’
44. ‘These metals occurs in the earth in the form of sulfides
45. such as copper sulfide
46. lead sulfide
47. and zinc sulfide (ZnS).’
48. ‘These groups are the silicate minerals
49. carbonate minerals
50. and halides.’
51. ‘During primary sulphate assimilation in chloroplasts
52. sulphate is reduced via sulphite to the organic sulphide which is used for cysteine biosynthesis.’
53. ‘One is a copper sulfate assemblage
54. which is generally associated with copper carbonates
55. cuprite
