چکیده
A step towards minimizing the environmental pollution of leather tanning , chrome shavings wastes were treated with Li2CO3 to extract technical or industrial gelatin as an added value material. Isolation and characterization obtained from chrome-tanned done. The alkali hydrolysis products obtained, showed good physical chemical properties in terms gel strength, swelling thermal stability. optimum conditions using found be 5 hr. extraction at 80°C, time one day pH 9.5. yield was over third original starting waste

Separation of motor oils, oily wastes and hydrocarbons from contaminated water by sorption on chrome shavings.
In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...
متن کاملPreliminary Results on the Use of Leather Chrome Shavings for Air Passive Sampling
A new passive sampler based on low-density polyethylene (LDPE) layflat tube filled with chrome shavings from tannery waste residues was evaluated to determine volatile organic compounds (VOCs) in indoor and outdoor areas. VOCs were directly determined by head space-gas chromatography-mass spectrometry (HS-GC-MS) without any pretreatment of the sampler and avoiding the use of solvents. Limit of ...
