Cellulose nanocrystals (CNCs) have unique and diverse applications in the various fields of developing nanomaterials. In this work, cellulose nanocrystals were extracted from millet husk residue waste using a homogenized acid hydrolysis method. The effects of the process variables namely; homogenization speed, acid concentration and acid to cellulose ratio on the yield and swelling capacity were investigated and optimized using the Box Behnken design method in response surface methodology. The cellulose and nano-cellulose obtained were characterized using transform infrared microscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The numerical optimization analysis results showed that the maximum yield of CNCs from cellulose was 93.12 % and obtained at homogenization speed, acid concentration, and acid to cellulose ratio of 7464.0 rpm, 63.40 wt %, and 18.83 wt % respectively. The maximum swelling capacity of 2.81 % was obtained at homogenization speed, acid concentration, and acid to cellulose ratio of 8000 rpm, 62.5 wt %, and 25 wt % respectively. A mathematical model was obtained to predict the yield and the swelling capacity of cellulose nanocrystals with R2 of the value of 98.9 % and 97.9% respectively. The TGA showed that the thermal stability of cellulose was higher than that of CNCs, FTIR results showed functional groups of CNCs and cellulose were similar, SEM image of CNCs is porous and displayed narrow particle size and needle-like morphology as compared to cellulose and XRD pattern presented an increase in the intensity of CNCs.

“…钴少见独立矿床, 目前主要为镍矿及铜矿的副产品, 生产量受市场对铜和镍需求影响, 因而会导致周期性供给不平衡. 我国钴矿资源分布地区较多 [9] , 其中伴生于岩浆铜镍硫化物矿中的钴主要分布在甘肃、新疆、吉林、陕西、云南、四川等地; 与铁、铜矿伴生的钴资源分布在四川、青海、山西、河南、广东、安徽等地 [10] ; 钴铜矿主要是吉林大横路钴矿 [11] 和湖南东部独立钴矿 [12] ; 富钴矽卡岩矿床主要发育在东昆仑地区 [13] 、长江中下游 [14] 和冈底斯地区 [15] . 本文对钴的地球化学特征、各类钴矿的地质特征、钴元素的迁移-富集机制和各类富钴矿床的成因进行综合分析, 并提出下一步对富钴矿床研究的展望.…”
