An adsorbent comprising at least two types of covalently bound antigens having the ability to bind at least one component present in a blood flow or blood plasma flow passing through said adsorbent is disclosed, as well as a column containing said adsorbent, a kit containing said column in a sealed plastic bag, a method for the production of said kit, a method for reduction or elimination of undesired blood group specific antibodies or autoimmune antibodies in connection with autoimmune diseases, a method for treatment of myasthenia gravis, and a method for treatment of rheumatoid arthritis.

The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke of cigarette, beedi, hookah. The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.

A process for deodorizing a rosin ester composition is disclosed. The process employs an adsorptive bed containing an adsorbent material. The adsorbent material comprises silica adsorbent having an average pore size between 50-200 Å, BET surface area of at least 300 mm.sup.2/g, pore volume of 1.20 to 3.00 cc/g, and a silanol [Si—OH] level of 0.5 to 5 unit/nm.sup.2. The deodorized rosin ester composition has an odor intensity reduction of at least 1 unit on odor intensity scale of Offensive Odor Control Act as compared to the rosin ester feedstock. In embodiment, the deodorizing treatment comprises using multi-staged adsorbent system with an adsorbent column having multiple layers of different adsorbent materials.

A method of performing dialysis includes: recirculating a dialysis fluid from a patient or a dialyzer for at least two cycles, each cycle contacting the dialysis fluid first with a zirconium phosphate layer followed by at least one of a urease layer, a zirconium oxide layer, or a carbon layer; storing the recirculated dialysis fluid in a storage container; and transferring the dialysis fluid from the storage container to the patient or the dialyzer. In one example, the zirconium phosphate layer and the at least one of the urease layer, the zirconium oxide layer, or the carbon layer is provided by a sorbent cartridge.
