Confirmation of heavy metal ions in used lubricating oil from a passenger car using chelating self-assembled monolayer

Used lubricating oil regeneration by various solvent extraction techniques

“…Lubricants used in internal combustion engines could be injured by various strains, depending on operating conditions, fuel quality, ambient conditions and operating parameters [1]. Without the appropriate treatment, the used oil will tend to be discarded that degrades the environment [2].…”

Optimization of acidic activated conditions for natural clay and its application in waste oil bleaching

“…Lubricating oil that has good characteristics shows a very major role in the industry. Lubricants used in internal combustion engines could be offended by various strains, depending on operating conditions, fuel quality, ambient conditions and operating parameters (Ko,Y.G.,2006), .Without the suitable treatment, the used lubricating oil will be subject to be discarded that degrades the environment (Ogbeide,S.O.,2010), (Hamad ,A.,2005). So, recycling and rerefining of waste oil into fresh lubricating oil may be auditable choice for protecting the environment from hazardous waste.…”
