SEM and X-ray analysis of surface microstructure of a natural leather processed in a low temperature plasma

Removal of As(V) and Cr(VI) from aqueous solutions using solid waste from leather industry

“…The micrograph of the wet blue leather waste (Fig. 2a) presented different morphology from the natural leather related in the literature [17,18]. The fibrous aspect of this material is due to presence of chromium in the leather [17].…”

“…2a) presented different morphology from the natural leather related in the literature [17,18]. The fibrous aspect of this material is due to presence of chromium in the leather [17]. The protein-like structure of the material is evidenced by the signals in 1655 cm −1 relative to the carbonyl group (C O) and in 1540 cm −1 to the N-H group [19] on the infrared spectroscopy (Fig.…”

Incorporation of mineral phosphorus and potassium on leather waste (collagen): A new NcollagenPK-fertilizer with slow liberation

“…4a) presented a different morphology from the natural leather (without chromium) related in the literature [20]. The fibrous aspect of the wet blue waste is probably due to presence of chromium in the leather [19].…”

Comparable Evaluation of Leather Waterproofing Behaviour upon Hide Quality. II. Influence of Finishing on Leather Properties

“…The hair pores are clearly visible without any surface deposition of tanning agents. However, the appearance of the fibres is related to the leather processing, through which it had passes [24,25]. For leathers TKO-1uF and NO-2uF the coatings appear less fibrous and are more robust than in the case of the leather TKO-2uF.…”
