“…This work proposed a new route of bentonite sodium intercalation under low-temperature and restricted time preparation to produce an adsorbent to SLS waste. Removal of SLS waste is demanding due to the high volume of waste disposed of, triggering several disadvantages: life health, water quality, and increasing undesirable foam [20,21]. The economic discovery of adsorbent material applied in SLS waste treatment was established as a bright solution [22].…”

In this work, the Sumatera bentonite was sodium-pillarized in a new low-temperature and restricted time preparation route and then applied in anionic surfactant sodium lauryl sulphate removal. Structure characterization used Fourier Transform Infra Red (FT-IR), Scanning Electron Microscope - Energy Dispersive X-ray (SEM-EDX), X-ray Diffraction (XRD), and Brunauer–Emmett–Teller (BET) analysis. A strong peak at 22° and 35.66° in XRD analysis was detected as Sodium-pillar that increased crystallinity, then the functional changes of dehydration in lattice structure were detected in 1013 cm−1 by FTIR analysis. The morphology and compositional transformation were analyzed by SEM-EDX and BET analysis, denoted by increasing particle shape and sodium intercalant composition homogeneity. Moreover, the surface area increased from 61.791 to 66.086 m2/g. The sodium lauryl sulphate adsorption by bentonite-Na reached maximum capacity at 8.403 mg/g, which is higher than the pristine bentonite (5.747 mg/g) under the optimum condition. The adsorption mechanism is feasible, endothermic, and conformed to the pseudo-second-order and Freundlich adsorption model. The new route proposed for sodium intercalation effectively improves the Sumatera bentonite adsorption ability to remove sodium lauryl sulphate waste.

Background: High pressure injection injury to the hand with paint leads to amputation rates near 48%. Historically, authors utilized saline irrigation alone, but have high reoperation rates. We conducted a cadaveric study to determine the ideal detergent for effective paint removal from the soft tissue. Methods: Two cadaveric hands were amputated from the same cadaver. The left and right hand digits were injected with flat white latex-based paint and flat white oil-based paint, respectively. Each digit received a longitudinal incision and was scrubbed for 120 seconds with 50 mL of a randomly assigned detergent and no detergent (saline) as the control. After achieving a lather, each finger was cleansed with 50 mL saline before being evaluated by two blinded hand surgery faculty. Reviewers assessed the washouts as adequate or inadequate, in order to generate a Kappa statistic and measure inter-rater reliability prior to ranking each digit (1 through 5) (ie, 1 = most paint-free soft tissue). Results: The two hand faculty had an inter-rater reliability of 0.70. Both reviewers ranked povidone-iodine 10% or Johnson & Johnson shampoo as the best irrigant for latex-based paint. In oil-based paint, povidone-iodine 10%, Johnson & Johnson, & Techni-care were ranked as top three. All reviewers reported detergents were better than saline alone. Conclusions: The addition of detergent created an irrigant that removed both latex- and oil-based paint better than normal saline alone. Based on these results, surgeons treating high-pressure injection injury should consider using Povidone-Iodine 10% or Johnson & Johnson baby shampoo for latex- or oil-based paint.
