“…It can be seen from Fig 9(a) that the characteristic absorption peaks of barite are at 1185 cm -1 , 1076 cm -1 , 865 cm -1 , and 609 cm -1 . The peaks at 1185 cm -1 and 1076 cm -1 are stronger symmetric telescopic vibrational absorption peaks induced by SO 4 2 -, the peak at 865 cm -1 is an asymmetric telescopic vibrational absorption peak induced by SO 4 2- , and the peak at 609 cm -1 is an in-plane bending vibrational absorption peak [ 50 , 51 ].…”

High-density waste drilling fluid contains an abundance of recyclable weighting reagents, direct disposal can pollute the environment. In this paper, the primary mineral composition of a high-density waste drilling fluid from a well in the southwest oil and gas field was analyzed. This paper proposes β-cyclodextrin (β-CD) as a depressant for the recovery of barite from waste drilling fluid. The recovery process was investigated through inverse flotation experiments, and the mechanism was analyzed using zeta potential, contact angle analysis, and FTIR. The flotation experiments showed that under the SDS flotation system, when the pH was 9.0 and the amount of depressant β-CD was 900 g/t, the barite recovery and density reached the highest values, which were 87.41% and 4.042 g/cm3, respectively. Zeta potential experiments, contact angle analysis, and FTIR analysis indicate that β-CD adsorbed onto barite through enhancing the hydrophilicity of barite, electrostatic force adsorption, and strong adsorption, which could not be displayed by SDS through competitive adsorption. Furthermore, β-CD exhibited a selective inhibitory effect on barite and enabled reverse flotation. The mechanism model of the flotation separation process was established.

“…A variety of HA-based pH-sensitive drug carriers have been developed, as well as drug carriers with multiple roles in detection and treatment. For example, Wan et al 18 grafted functional groups onto HA microspheres via host−guest reaction, endowing the carrier cells with dual functions of imaging and pH responsiveness. Lai et al 19 used calcium carbonate as a template to prepare HA microspheres, which exhibited high drug loading capacity and pH-responsive drug release behavior.…”

Titanium carbide MXene quantum dots (MQDs) possess intrinsic regulatory properties and selective toxicity to cancer cells. Here, MDQs were selected for the modification of hydroxyapatite (HA) microspheres, and MXene quantum dots-modified hydroxyapatite (MQDs-HA) hollow microspheres with controllable shapes and sizes were prepared as bone drug carriers. The results show that the prepared MQDs-HA hollow microspheres had a large BET surface area (231.2 m 2 /g), good fluorescence, and low toxicity. In addition, MQDs-HA showed a mild storage−release behavior and good responsiveness of pH and near-infrared (NIR). Thus, the MQDs-HA hollow microspheres have broad application prospects in the field of drug delivery and photothermal therapy.
