In a similar manner EDTA is used in the cement industry for the determination of free lime and free magnesia in cement  and clinkers.The solubilisation of Fe3+ ions at or below near neutral pH can be accomplished using EDTA. This property is useful in agriculture including hydroponics. However, given the pH dependence of ligand formation, EDTA is not helpful for improving iron solubility in above neutral soils. Otherwise, at near-neutral pH and above, iron(III) forms insoluble salts, which are less bioavailable to susceptible plant species. Scrubbing
Aqueous [Fe(EDTA)]− is used for removing ("scrubbing") hydrogen sulfide from gas streams. This conversion is achieved by oxidising the hydrogen sulfide to elemental sulfur, which is non-volatile:

2 [Fe(EDTA)]−  +  H2S  →  2 [Fe(EDTA)]2−  +  S  +  2 H+In this application, the iron(III) centre is reduced to its iron(II) derivative, which can then be reoxidised by air. In similar manner, nitrogen oxides are removed from gas streams using [Fe(EDTA)]2−. The oxidising properties of [Fe(EDTA)]− are also exploited in photography, where it is used to solubilise silver particles. Ion-exchange chromatography
EDTA was used in separation of the lanthanide metals by ion-exchange chromatography. Perfected by F. H. Spedding et al. in 1954, the method relies on the steady increase in stability constant of the lanthanide EDTA complexes with atomic number. Using sulfonated polystyrene beads and Cu2+ as a retaining ion, EDTA causes the lanthanides to migrate down the column of resin while separating into bands of pure lanthanides.
Signs of infection require to be considered such as development of grey or yellow tissue, purulent discharge, unpleasant smell, sinus, undermined edges and exposure of bone or tendon.Identification of diabetic foot in medical databases, such as commercial claims and prescription data, is complicated by the lack of a specific ICD-9 code for diabetic foot and variation in coding practices. The following codes indicate ulcer of the lower limb or foot:
707.1 Ulcer of lower limbs, except pressure ulcer
707.14 Ulcer of heel and midfoot
707.15 Ulcer of other part of foot
707.19 Ulcer of other part of lower limbOne or more codes, in combination with a current or prior diagnosis of diabetes may be sufficient to conclude diabetic foot:

250.0 Diabetes Mellitus
250.8 Diabetes with other specified manifestations

Classification
Diabetic foot ulcer is a complication of diabetes. Diabetic foot ulcers are classified as either neuropathic, neuroischaemic or ischaemic.Doctors also use the Wagner Grades to describe the severity of an ulcer. The purpose of the Wagner Grades is to allow specialists to better monitor and treat diabetic foot ulcers. This grading system classifies Diabetic foot ulcers using numbers, from 0 to 5. Wagner Grades 0 through 5 are as follows:
0. No diabetic foot ulcer is present, but there is a high risk of developing one. 1. A surface ulcer involves full skin thickness, but does not yet involve the underlying tissues. 2. A deep ulcer penetrates past the surface, down to the ligaments and muscle. There is no abscess or bone involved yet. 3.
