“…Stepwise hydration of interlayer cation in MMT enabled intercalation with positively charged molecules. Although many adsorbents are reported for removal several pollutants from aqueous solution: Cd +2 and Pb +2 [20,21], Cr(VI) ion [22][23][24][24][25][26][27][28][29]; pb(II) ions [30,31], reactive dyes [32,33], MMT clay bisorbent for adsorption of 5-[4-bromobenzylidene amino)-1, 3, 4-thiadiazole-2-thiol (BATT) is not reported yet, ecofriendly and keeping environmental safety, biodegradability, availability, etc.…”

The synthesized heterocyclic compound: 5-[4-bromobenzylidene amino)-1, 3, 4-thiadiazole-2-thiol abbreviated as BATT possessed good antibacterial activity for various Gram-negative and Gram-positive bacteria. In addition to potent antitumor activity to breast cancer, for the first time, the novelty of this study is facile low-cost formulation of safe antitumor drug delivery system (DDS) for breast cancer from such simple heterocyclic compound. Heterocyclic compound is efficiently and spontaneously incorporated into MMT clay polymer matrix forming novel therapeutic nanocomposite DDS for breast cancer. BATT successfully intercalates MMT clay polymer matrix. Electron donation ability of nanocomposites is confirmed by cyclic voltammetry in terms of small peak-to-peak redox potential $$\Delta E_{{{\text{peak}}}}$$ Δ E peak . Adsorption of BATT on clay is carried out by batch adsorption method. Better adsorption strength at low pH 2 decreased with increasing pH. Adsorption data are analyzed by multiple mathematical models. MMT clay is an efficient carrier polymer heterogonous adsorbent for BATT at optimum conditions: contact time 2.0 h, pH 2 and initial concentration up to 1200 ppm. Adsorption rate constant, k2 equals 14.6 $$\times$$ × 10–3 and qe 19 mg g−1 (R2 0.999). pH of zero charge of MMT at pH 3 reflected adsorption mechanism of MMT. At pH 2, BATT is loaded on MMT by physi- and chemisorption. At pH 4, BATT is loaded on MMT by chemisorption.

“…Due to the high cost of most of these materials, the need to study and develop low-cost adsorbent materials has increased [29]. Hence, special attention has recently been diverted toward the use of natural materials, agricultural waste and industrial waste as promising alternative adsorbents for the removal of metal ions, either in their natural form or after subjecting them to some modification [30][31][32][33][34][35][36][37][38].…”

In this study, a highly effective hybrid adsorbent composite based on low-cost fuller’s earth (FE), aluminum silicate (AS) and chitosan (CS) was prepared using a facile method. The prepared composite was applied to adsorb lead (Pb2+) and copper (Cu2+) ions from aqueous solutions. Several analyses such as Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the composite. The adsorption efficiency of the prepared composite was investigated at different operating conditions. Moreover, the adsorption isotherm/kinetic models and adsorption thermodynamics of the composite were examined. The results showed that the pseudo-second-order kinetic model described well with the obtained data and the adsorption equilibrium can be better described by Langmuir isotherm model with maximum adsorption capacities of 305.5 and 284.2 mg/g for Pb2+ and Cu2+, respectively. The obtained data demonstrated that the prepared composite is an efficient and kinetically fast metal ion removal with high adsorption capacity and recovery efficiency. Graphical abstract

“…24 Recently several natural materials have been developed showing economic and environmental interest including horn snail, mangrove crab shell powder, bagasse-bentonite, Archontophoenix alexandrae, silica@mercapto, Bali cow bones-based hydrochar and microalgae for example Chlorella vulgaris. [25][26][27][28][29][30][31][32][33][34] These advancements show great promise in the eld of heavy metal removal and offer hope for cleaner water sources in the future and can be combined with other more stable materials for water treatment.…”
