NOVELTY - Sorbent material comprises Primary Secondary Amine (PSA)-functionalized metal oxide network produced from hydrolysis and condensation of precursors, precursors comprising one or more primary metal oxide precursor (I) and one or more PSA-functionalized metal oxide precursor. The sorbent material further comprising carbonaceous and/or non-carbonaceous particles being encapsulated within network; hydrolysis and condensation are carried out in the absence of an independent base catalyst; and one or more PSA functional group and carbonaceous and/or non-carbonaceous particles being homogeneously distributed within network. USE - Sorbent material for absorbing or adsorbing sample component (claimed), used in the fields of food analysis, pharmaceutical analysis, environmental analysis, toxicological analysis, clinical analysis, forensic analysis, as well as environmental remediation and antimicrobial and/or other protective coatings in food or pharmaceutical packaging. ADVANTAGE - The sorbent material being capable of removing an organic acid and color pigments from a sample comprising a mixture of analytes in a single step, has more economical and controllable condensation step in the sol-gel manufacturing process that allows for increased loading of PSA functional groups as well as incorporation of carbonaceous and/or non-carbonaceous particles, has a sponge-like porous architecture that allows elution solvents to permeate within itself, further contributing to improved efficiency, and does not require a high volume of organic solvents. DETAILED DESCRIPTION - Sorbent material comprises Primary Secondary Amine (PSA)-functionalized metal oxide network produced from hydrolysis and condensation of precursors, precursors comprising one or more primary metal oxide precursor (I) and one or more PSA-functionalized metal oxide precursor. The sorbent material further comprising carbonaceous and/or non-carbonaceous particles being encapsulated within network; hydrolysis and condensation are carried out in the absence of an independent base catalyst; and one or more PSA functional group and carbonaceous and/or non-carbonaceous particles being homogeneously distributed within network. M=silicon, titanium, aluminum, zirconium, tantalum, germanium, barium, gallium, indium, thallium, vanadium, cobalt, nickel, chromium, copper, iron, zinc, boron, lanthanum, or niobium; and at least two of R1, R2, R3, and R4=alkoxy, carboxyl, or hydroxy; remaining R1, R2, R3, and R4=absent, H or alkyl moieties, arylene moieties, cyanoalkyl moieties, fluoroalkyl moieties, phenyl moieties, cyanophenyl moieties, biphenyl moieties, cyanobiphenyl moieties, dicyanobiphenyl, cyclodextrin moieties, crown ether moieties, cryptand moieties, calixarene moieties. INDEPENDENT CLAIMS are included for: (1) a method of synthesizing a PSA-functionalized sorbent material, which involves mixing a primary metal oxide precursor and at least one acid catalyst to obtain a sol mixture; combining sol mixture and a PSA-functionalized metal oxide precursor without a separate base catalyst to obtain a gel to form the PSA-functionalized sorbent material; and (2) a method of absorbing or adsorbing a sample component, which involves providing the sorbent material; and contacting sorbent material with solid, liquid, or gas comprising component.
