  Synthesis and Characterization of Zn/Al, Zn/Fe, and Zn/Cr Layered Double Hydroxides: Effect of M3+ ions Toward Layer Formation

summary:
  Based on its existence, nature layered materials such as kaolinite and bentonite (Taher et al., 2018, 2017) then synthesized layered material such as layered double hydroxides or hydrotalcite (Jadhav et al., 2007; Lesbani et al., 2018; Palapa et al., 2018b). Generally, layered double hydroxides have a general formula of M2+ M3+ (OH)2(An-)x/n.yH2O where M3+ and M2+ are repre- sented the trivalent metal and divalent metal, respectively (Tichit et al., 2019; Lins et al., 2018).

A blank solution was prepared by mixing the standard reagent for 100 mL of sample (consisting of 1000 `L KBr-KBrO3 and 50 `L hydroxylamine hydrochloride 12%) and dd water up to a volume of 100 mL. Variation of mercury concentration was obtained by mixing some mercury stock solutions with standard reagent and diluted with dd water according to the required concentration.

  Most models of SCP only deal with the ability to set optimal facility location if the only parameter known would be the distance between facilities and distance between facilities and population (Sitepu et al., 2019). Furthermore, for the number of hospitals in each Sub- District will be dened as (h̃i), for example, Alang-Alang Lebar Sub-District has 1 hospital (h̃1), Bukit Kecil Sub-District has 2 hospitals (h̃2), and so on until the Jakabaring Sub-District has 0 hospitals (h̃18) as stated in Table 1. Table 2 displays the distance between the request point and ED location with a distance unit of kilometers (km), it can be seen in the distance between Alang-Alang Lebar (x̃1) to RSK Ernaldi Bahar (ỹ1) is 1.7 km, and so on until Jakabaring (x̃18), (Myria Hospital) (ỹ23) is 15 km.

Pictures of the number of colonies before (control) and after treatment with treatment time variations can be seen in Figure 4. The treatment of time variation and distance variation shows that there is an eect of non-thermal plasma treatment of SDBD.

  Based on Table 3, the kinetic data shows that the linear re- gression value (R2) of the pseudo-second-order (PSO) tends to be closer to 1 value than to the pseudo-first-order (PFO) kinetic model, so it concluded that RhB adsorption in bentonite-based adsorbent follows the PSO model kinetics. Based on Table 4, the Freundlich isotherm model shows a linear regression value (R2) closer to the value 1 than the Langmuir isotherm model for RhB adsorption, indicating Figure 6.

  Based on the above background, the aim of this study is to determine and quantify (+)-catechin using HPLC, followed by antioxidant activity using DPPH methods in the infusion of S. quadrida stem bark. Approximately 10 mg of water extract of S. quadrida stem bark was mixed with 100 mg of KBr and packaged into sample pellets and then read by the FTIR spec- trophotometer (Perkin Elmer, 1302F6802).
